For a Commenting Profile That Won't Stick

Have you ever tried to comment on a blog post only to have your profile not load? No matter what you do, you can't get the site to recognize you, so you're stuck commenting as "anonymous" (if the blog actually allows anonymous comments, otherwise you're just out of luck). 

No, sorry, I don't have a fix for you. A few weeks back, I attempted to tackle the issue by asking if you had your cookies enabled. Alas, I don't think this solved the problem (but if you haven't tried that, try it first). But I was reminded of something a school IT guy told me. They search and research and ask various people in the hopes of finding someone who has fixed an issue. 

While visiting my brother last month, I asked him the question. He did not have an answer for me, but he was able to articulate a question and input it into Google's Gemini. (Yes, I hate AI, but it gave an answer. It has to be useful for something.) 

So, if you're stuck and have tried everything, there's one more thing to try. 

But first I'll post the answer just in case some of you find it useful. 

The question: Mac user reporting that their profile won’t stick. When they try to log in with user and pass, it doesn’t log them in. It vanishes. Is this more of a browser issue?

Because we were wondering if it was a browser thing (as some of you have reported that one browser works just fine while you have issues with another), we included that information. And Gemini replied that yes, it most likely is. This is good news as if you're having commenting issues, it might be a great time to download a different browser and use it instead. The answer Gemini gave: 

Yes, this is almost certainly a browser issue, specifically tied to how Mac browsers (most notably Safari) handle cross-site tracking and cookie authentication.

Blogger frequently drops users into a "login loop" or vanishes the session immediately after authentication because it negotiates between two separate domains: [www.blogger.com](https://www.blogger.com) (the dashboard) and blogspot.com (the published content). If the browser blocks the communication between these domains, the session data won't stick.

So, basically, when you go to log in (so Blogger recognizes you), your info vanishes because of how the browser communicates with the website. Gemini gave some suggestions on how to fix it. 

1. The Safari Culprit: Cross-Site Tracking

Safari has an aggressive native privacy feature called Intelligent Tracking Prevention (ITP). If they are using Safari, it routinely blocks the cross-domain authentication tokens required by Blogger.

The Fix: Have them go to Safari > Settings (or Preferences) > Privacy and temporarily uncheck "Prevent cross-site tracking".

After unchecking it, they should clear their history, restart Safari, and try logging in again.

This is for the specific Mac issue. If you're not on Mac, skip this and move on to #2. 

2. Third-Party Cookie Restrictions (Chrome / Arc / Brave)

If they are using Chrome or a Chromium-based Mac browser, strict settings or extensions might be blocking third-party cookies, which prevents the Google authentication state from transferring to Blogger.

The Fix: Have them check chrome://settings/cookies and ensure third-party cookies aren't completely blocked, or add [*.]blogger.com and [*.]google.com to the allowed sites list.

This is for Mac, but it is probably similar for Windows-based systems. Then...

3. State/Onboarding Profile Corruption

Sometimes the login "vanishes" because the Google account is successfully authenticating, but the Blogger backend is bouncing them because the profile lacks a required Display Name or is stuck in an onboarding state.

The Fix: Have them open a new tab and go directly to [https://www.blogger.com/onboarding](https://www.blogger.com/onboarding) or [https://www.blogger.com/profile.g](https://www.blogger.com/profile.g). If it forces them to enter a display name, completing that step will instantly fix the dashboard drop-out.

I wonder if the above is anyone's issue. I'm sure someone is having that issue. And finally, the "quickest triage step": 

Have them try to log in via a completely different browser (like Firefox) or an Incognito/Private window with all extensions disabled. If that works seamlessly, you've confirmed it's a localized cookie/privacy setting on their primary browser.

I hope this helps. If you're having this issue and this helps, or if you're having this issue and this doesn't help, please let me know. I'll keep my eyes and ears open and if I come across another way this could be solved, I'll let you know.
