[SOLVED] Your OpenID Credentials Could Not Be Verified — Blogger & WordPress Fix

Picture this: you just read the most helpful blog post in the world, you are fired up to leave a thoughtful comment, you enter your blog URL as OpenID, hit submit — and BAM. Your screen shows: "Your OpenID credentials could not be verified." You stare at it. You click retry. Same message. You try again. Same. At this point, you have gone through all five stages of grief in about forty-five seconds. Sound familiar? You are absolutely not alone, and more importantly, this problem has a fix that takes less than two minutes. So take a deep breath, because we are about to solve this once and for all. Bloggers who actively comment on other blogs grow their audience much faster — and learning the right blog design tips and tricks for successful blogging goes hand in hand with knowing how to engage properly with your community.

The OpenID credentials could not be verified error affects both Blogger (BlogSpot) users and WordPress bloggers equally. It is not a problem with your blog's plugins, your browser cache, or your internet connection. It is simply a matter of missing a few tiny lines of HTML code in your blog's template. The system tries to verify your OpenID URL against your blog's HTML code and when those specific link tags are not there, the verification fails every single time. Understanding this helps because fixing blog comment errors is an important part of being a good, active member of the blogging community — and an active commenter is someone who builds real relationships and grows real authority. For bloggers who want to avoid all the common pitfalls while growing their presence online, knowing about the most common blogging mistakes beginners make and how to fix them is just as valuable as knowing how to fix technical errors.

In this guide, we are going to explain exactly what OpenID is, why this error happens, how to fix it permanently on both Blogger and WordPress, what alternatives you can use in today's comment systems, and how to make sure your comments always build your blog's traffic and SEO authority. Let's get into it!

What Is OpenID and How Does It Work?

Let's start with the basics before we jump into the fix. OpenID is an open standard authentication protocol that allows you to use a single URL — typically your blog or website URL — as your login identity across multiple websites. Instead of creating a new username and password on every site you want to comment on, you simply enter your blog URL, and the destination site verifies your identity through your blog's OpenID settings.

Think of OpenID like a digital passport. Your blog URL is your passport number. When you arrive at a new site and want to comment, you present that passport. The site contacts your "home country" (your blog) to confirm you are who you say you are. If everything checks out, you are allowed in. If the verification fails — which is exactly what happens with this error — you get turned away at the door.

OpenID-enabled blogging platforms like Blogger and WordPress support this authentication method, making it easy for bloggers to comment across the web using their blog URL as their identity. This is great because it means your blog link appears in comments across many websites, which helps build your online presence, drives referral traffic back to your blog, and can even improve your SEO through comment backlinks. The connection between active commenting and audience growth is real — and understanding how to make your blog memorable and build your brand online shows you exactly why being an active community participant matters so much for long-term growth.

Why Does the "Your OpenID Credentials Could Not Be Verified" Error Happen?

Now that you understand what OpenID does, let's understand why this specific error appears. The OpenID verification error happens because the website you are trying to comment on cannot find the required OpenID authentication tags in your blog's HTML source code.

When you enter your blog URL as OpenID, the destination website visits your blog URL and looks inside your page's HTML head section for two specific link tags: an openid.server tag that points to your OpenID server, and an openid.delegate tag that specifies your exact blog URL as the delegated identity. If either of these tags is missing from your HTML, the server reports back: "Sorry, we could not verify this OpenID." And that is the error you see on your screen.

This is not a serious security issue and it does not mean anything is wrong with your blog. It simply means these two specific tags were never added to your template — which is completely normal for blogs set up without OpenID configuration in mind. The fix is quick, clean, and permanent. Let's do it!

Fix "Your OpenID Credentials Could Not Be Verified" — Step-by-Step

Good news: this fix requires adding exactly two lines of HTML code to your blog template. That's it. Two lines. No plugins, no tools, no technical expertise needed. Just follow these steps carefully and your OpenID will work perfectly afterwards.

1. Open the HTML code / template editor of your blog or website.
   
   
2. Find the <head> section at the top of your template's HTML.
   
   
3. Add the following two lines of code just below the opening <head> tag:
   <link href='https://www.blogger.com/openid-server.g' rel='openid.server'/>
   <link href='YOUR-BLOG-URL-HERE' rel='openid.delegate'/>
   
   
4. Replace YOUR-BLOG-URL-HERE with your actual full blog URL (for example: https://www.yourblogname.com).
   
   
5. Save your template changes. That is all — you are done!

The first line tells any OpenID-enabled site which OpenID server handles authentication for your blog. The second line specifies your exact blog URL as the delegated OpenID identity. Together, these two lines give external websites everything they need to verify your identity when you comment using your blog URL.

After saving, try leaving a comment on another Blogger site using your blog URL as OpenID. You should now pass verification smoothly with no error. The fix is permanent — you only need to do this once. And while you are in your template editing it, it is a great opportunity to also check on other technical improvements that help your blog perform better. For example, making sure your meta tags are properly set up to improve your PageRank and SEO performance is one of those small but high-impact optimizations that every blogger should have in place.

How to Fix OpenID on Blogger (BlogSpot) — Detailed Steps

If your blog is hosted on Blogger (BlogSpot), here is the exact step-by-step process for finding your template HTML and adding the fix:

Step 1: Log in to your Blogger Dashboard.

Step 2: Go to Theme (or "Template" in older Blogger versions) in the left sidebar menu.

Step 3: Click the Edit HTML button. This opens your blog's full HTML template in an editor.

Step 4: Use Ctrl+F (or Cmd+F on Mac) to open the search box inside the editor. Type <head> and press Enter to jump directly to that tag.

Step 5: Place your cursor right after the <head> tag and add a new line. Then paste the two OpenID link tags shown in the fix section above.

Step 6: Make sure to replace YOUR-BLOG-URL-HERE with your actual BlogSpot URL (for example: https://yourblogname.blogspot.com) or your custom domain if you have one set up.

Step 7: Click the Save theme button at the top right. Done!

One thing to note for Blogger users: if you are using a custom domain (not the default .blogspot.com address), use your custom domain URL in the openid.delegate tag. The OpenID server tag always stays the same — only the delegate URL changes based on your actual blog address. If you have not set up a custom domain yet and want to make your blog look more professional, this complete guide to setting up a custom domain on Blogger with GoDaddy walks you through every step from start to finish.

How to Fix OpenID on WordPress — Detailed Steps

WordPress bloggers face the exact same OpenID error and the same fix applies — the code just needs to go in a slightly different place depending on your setup. Here are two methods for WordPress:

Method 1: Edit Your Theme's header.php File

Step 1: Log in to your WordPress Admin Dashboard.

Step 2: Go to Appearance → Theme Editor (or Appearance → Editor in newer WordPress versions).

Step 3: In the file list on the right side, find and click on header.php.

Step 4: Find the <head> tag near the top of the file. Add the two OpenID link tags immediately after it.

Step 5: Replace YOUR-BLOG-URL-HERE with your WordPress site's full URL (for example: https://www.yourwordpresssite.com).

Step 6: Click Update File to save your changes.

Method 2: Use a WordPress Plugin (Easier for Non-Technical Users)

If you are not comfortable editing theme files directly — which is completely valid — there are WordPress plugins specifically designed to handle OpenID authentication. Search for "OpenID" in the WordPress plugin repository, install a well-reviewed plugin, and follow its setup instructions. This method requires zero code editing and works just as well.

Important note for WordPress users: if you update or switch themes, your header.php edits may be lost. For a permanent solution that survives theme updates, either use a child theme to make your edits, or stick with the plugin method. To avoid making technical mistakes on your WordPress blog that could cause bigger problems down the line, it is worth reading about the most common WordPress mistakes beginners make and how to fix them — catching these early saves you hours of troubleshooting later.

Why Commenting on Other Blogs Still Matters for Your SEO and Traffic

Now that your OpenID is fixed, let's talk about WHY you should be using it regularly. Commenting on other blogs is not just about being social — it is a real, working strategy for building blog traffic, growing your audience, and even improving your SEO through comment backlinks. When done consistently and genuinely, blog commenting is one of the most underrated growth tactics available to bloggers at any level.

When you leave a thoughtful, helpful comment on a blog in your niche, you introduce yourself to that blogger's audience. Readers who see your insightful comment get curious and click your name to visit your blog. This is direct referral traffic — visitors with zero cost and often very high engagement because they already know you have something interesting to say. Multiply this across dozens of different blogs in your niche over weeks and months, and the traffic compounds meaningfully.

From an SEO perspective, many blog comment sections allow dofollow comment backlinks — links that pass SEO authority from the blog you commented on to your own site. Even nofollow comment links have indirect SEO value because they drive real visitors who may then link to your content from their own sites. Comments also strengthen your reputation within a blogging community, which leads to guest post opportunities, collaboration invitations, and social shares — all of which have very real SEO impact. If you want to go deeper into building genuine blog traffic the smart way, these content marketing hacks that speed up blogging growth will give you a full toolkit to work with.

The most important rule of effective blog commenting: always add genuine value. Do not post two-word comments like "Great post!" or "Nice article!" Those add nothing, look like spam, and damage your reputation. Instead, write 2-4 sentences that extend the conversation, ask a relevant question, share a related experience, or respectfully add a perspective the original post missed. Meaningful comments get read, remembered, and clicked.

Modern Alternatives to OpenID for Blog Comments

While OpenID is still supported on many platforms, the commenting world has evolved significantly. Many modern blogs and websites now offer several alternative comment identity options that you should also know about:

Google Account / Gmail Sign-In: The most commonly used comment identity on Blogger-powered sites today. Signing in with your Google account is fast, familiar, and completely reliable — no OpenID tags required.

Disqus: A widely used third-party comment platform that works across both Blogger and WordPress sites. Your Disqus profile links back to your website, making it an effective tool for cross-site identity and referral traffic.

Name/Email/URL fields: Many WordPress sites allow you to comment by simply entering your name, email address, and website URL without any authentication at all. Always fill in your website URL field when commenting — this is a direct backlink to your blog.

Social login (Facebook, GitHub, LinkedIn): Some comment systems allow signing in with social accounts. While convenient, these do not always include a link back to your blog — so the OpenID or Name/URL approach is often better for traffic building purposes.

No matter which comment method you use, what matters most is the quality and consistency of your engagement. A blogger who leaves 10 thoughtful comments per week across their niche will see far more growth than one who publishes great content and then says nothing to anyone. Community participation is one of the fastest ways to grow a blog in the early stages — and it remains valuable at every stage of a blog's development. For bloggers who are still in the early stages of building their platform, this complete guide to becoming a successful blogger and making money online covers all the foundational steps you need to take to build a real, sustainable blogging career.

Tips for Making Your Blog Comments Count for SEO

Since you are now commenting with a properly verified OpenID (or one of the alternatives), let's make sure every comment you leave works as hard as possible for your blog's growth and visibility. Here are the most important tips:

Always use your real blog URL: Whether you are using OpenID, Name/URL fields, or any other method — always include your blog URL. This is your backlink. Do not skip it.

Use a consistent name and avatar: Use the same name you use on your blog and a professional, recognizable profile photo. Consistency builds familiarity, and familiar names get clicked more often.

Comment early on new posts: Being one of the first commenters on a new post means more people see your comment as the post gets more traffic over time. Set up Google Alerts or RSS feeds for your favorite blogs so you know when new content goes live.

Focus on high-traffic, high-DA blogs in your niche: A comment on a blog with 100,000 monthly visitors and a Domain Authority of 60 is worth far more to your traffic and SEO than a comment on a blog with 500 visitors. Prioritize quality over quantity. You can learn more about what domain authority is and why it matters for your blog's SEO to better understand which blogs are worth targeting in your commenting strategy.

Avoid keyword-stuffed anchor text in your name: Using "Best SEO Tips Blog" as your commenter name instead of your actual name or blog name is widely considered spammy and will get your comment deleted on most well-moderated blogs. Use your real name or your blog's brand name.

Follow up on your comments: If someone replies to your comment, reply back. Ongoing comment conversations build stronger relationships with both the blog owner and other readers — and they keep your comment visible as the thread gets longer.

Consistent, genuine blog commenting as part of a broader blogger outreach strategy opens doors to guest posting opportunities, collaborative content, social shares, and real friendships within your blogging community. These relationships are often worth more in the long run than any individual SEO tactic. For a deeper look at how the broader blogging journey teaches you real-world skills and opens real opportunities, these honest blogging lessons and life skills from professional bloggers are worth your time to read.

Troubleshooting: Still Getting the OpenID Error After the Fix?

Applied the fix but still seeing the error? Don't panic — here are the most common reasons it might still be happening and how to resolve each one:

1. Browser cache is showing old page data: After you save your template changes, your browser might still be serving a cached version of your blog that does not include the new code. Clear your browser cache completely, then try the OpenID comment again. Alternatively, test it using a different browser or an incognito/private window.

2. Wrong URL in the openid.delegate tag: Double-check that the URL you put in the openid.delegate tag exactly matches the URL of your blog — including whether it uses http:// or https://, and whether it has a www prefix or not. A mismatch of even a single character will cause verification to fail.

3. The code was pasted in the wrong place: The two link tags must go inside the <head> section of your template — not inside <body>. If they are in the wrong place, the OpenID verification crawler will not find them. Go back to your template and confirm their exact position.

4. Your blog's SSL/HTTPS setup is causing a mismatch: If your blog recently switched from HTTP to HTTPS (which is strongly recommended for security and SEO), make sure your openid.delegate URL uses the HTTPS version of your address, not the old HTTP version. SSL setup also affects how external tools verify your site. For Blogger users who want to speed up their blog while improving security and reliability, this guide to increasing Blogger speed and PageSpeed scores for better search rankings covers the performance and HTTPS improvements that every BlogSpot blogger should implement.

5. The destination blog has disabled OpenID commenting: Some blogs have turned off OpenID as a comment option entirely, especially those that have migrated to newer comment systems. If a blog no longer shows OpenID as a sign-in option, use the Name/URL method or sign in with Google instead.

6. Caching plugin conflict (WordPress only): If you are using a caching plugin on WordPress, it may be serving a cached version of your pages that does not include your new OpenID tags. Purge your entire site cache after making the template changes, and then test again. For broader WordPress performance and reliability improvements, checking your blog's overall speed and PageSpeed score after making any template edits is always a smart move.
