Gmail login fails

[Redglyph]

Description

Each day, I log in several Gmail accounts, and I log out at the end of the day.

Since May, there have been daily issues when logging in with Brave (not with any Chrome, Firefox, or Edge) in at least one of the accounts, sometimes more.

What is expected

1. First account

• Open the Gmail login page (http://mail.google.com/)
• Choose an account

I’m expecting to see the password form:

2. Additional account (after the first login):

• Open Gmail
• Click on the avatar (top right)
• select another account and click Sign In

There, I’m expecting the page below, and after clicking Next, the password form above.

What happens instead

What I often get instead is this:

Additional information

• When it’s the first account, one must reload the initial Gmail page.
• When it’s an additional account, it’s sometimes possible to get back, reload the page, and try again.

Sometimes, it takes several attempts before the password forms appears.

The problem appeared suddenly. Then it disappeared as suddenly when the bug “Users being logged out of sites” appeared for me, in September. It reappeared shortly after that other bug was fixed.

A bug issue has been created on GitHub (but has been ignored): https://github.com/brave/brave-browser/issues/46876

I frequently tried to reproduce this problem with other browsers but never could. I never saw this bug before May on Brave, either.

I contacted the support at Google, but they couldn’t help since Brave isn’t supported. They claimed they hadn’t changed anything.

Brave Version

Current version: Brave 1.83.112 (Official Build) (64-bit) Chromium: 141.0.7390.70

First version when the bug was observed: version 1.79.118 x64

OS (on different PCs):

• Windows 10 x64 22H2, Linux
• Linux Manjaro, 6.12.20-2-MANJARO, x86_64

No plugins, no shields, also tested with a fresh installation of Brave on both Windows and Linux.

It would be nice not to be ignored again.

Hi @Redglyph, thanks for reporting again, and for sharing the link with your issue. I’m surfacing with the team today, and will report back as I have any new info.

[Redglyph]

It looks like there wasn’t any feedback about that, then.

[Redglyph]

It’s always the same with you. One short message just to show someone replied, and then no news.

Fine, I suppose that’s it again, then.

What happens often now is that, instead of refusing the password form right away, clicking “Next” gives a form with the email login. So it apparently fails to recognize a part of the email information in the cookie, or something fails earlier than before.

And of course, this bug report is being ignored like the previous one.

Sometimes, Gmail also seems to think I’m logging onto another device.

This is really a nasty bug; too bad you wouldn’t fix it. I suppose it’ll take a number of people before you look at it.
