American Express Login Locked Out Only in Brave

Description of the issue: When I try to login to American Express I continue to get the below screen. If I try to login using Edge it goes right in. Also if I follow the prompts from amex and reset my password it loops back to this account locked page. When I called American Express they said my account does not show locked on their side and had me confirm I can get in using Edge.

I did not have an issue with this until I reformatted my computer, installed windows, installed brave. I assume it wasn’t an issue on an older version of Brave due to this behavior. Also I have the same problem using my work computer.

Exact URL of the website in question: https://www.americanexpress.com/en-us/account/login?inav=iNavLnkLog

Did the issue present with default Shields settings? (yes/no) Yes

Does the site function as expected when Shields are turned off? No, the problem still exists.

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no): I didn’t test this

Does the site work as expected when using Chrome? I don’t have chrome installed. It does work with Edge.

Brave version (check About Brave): 1.82.166

That message says its related to unsuccessful login attempts, seems server side? If you had bad attempts in another browser then switched to Brave, it wouldn’t fix this. Most sites will have a timeout, maybe wait a bit and retry to login?

Note, I don’t have a login to test here

The site works without giving me the login message when using edge. This appears to be a Brave problem since it works with a different browser.

On my work computer that has chrome installed. See screenshot below that chrome and edge work.

Topleft - Brave

Topright - Edge

Bottomleft - Chrome

If I open https://www.americanexpress.com/en-us/account/password/recover?locked=true

I get the same Your account has been locked due to too many unsuccessful attempts. To log in, please reset your password or retrieve your User ID.

But seems its reproducible on Firefox and Chrome (this page)

I didn’t use a bookmark to go to American Express. For each of those screenshots I searched American Express and clicked the first link that appeared. Then I clicked login, typed in credentials, and only brave gave me the locked account screen.

@Nickb1907 let me just confirm, you’re saying you have this issue on multiple devices and only on Brave?

Also maybe repeating a bit, but can you confirm whether:

  • Disabling Shields

  • Opening in a private window

  • Creating a second browser profile and using “as is” This would be three line menu → more tools → add new profile. This is a secondary profile to test, can delete after. Don’t add extensions or anything.

  • Install Brave Beta or Brave Nightly, does it happen there?

  • I know you mention Edge which might say something, but if none of the above make a difference, can you add Chrome just long enough to test if it logs in with no issue?

Am asking internally if someone has amex account to reproduce

Does the error show up on anything other webpage than https://www.americanexpress.com/en-us/account/password/recover?locked=true ?

The issue happens on my work pc and my personal pc using brave. They are synced together.

Tested with shields disabled - Same issue.

Tested in private window - Same issue.

Tested creating a new profile - Successful login with brave

Brave beta/nightly - I would prefer not to install more browsers so have not tested.

Edge/Chrome - See post 2 days ago. Tested brave/chrome/edge all on same computer (work) with only brave giving me the lock out screen. On my personal computer I only have brave and edge and it has the same behavior as the work pc.

Shield settings for “test” profile left and normal profile right. Also shields were on on test profile, on/off on normal profile.

@Nickb1907

  • Shields = If no difference even with it off, this means it’s very unlikely the issue has nothing to do with Shields

  • Private = This primarily tests cookies and extensions, with the bigger emphasis on cookies. If no change to issue, then usually can rule out one or both.

  • New Profile = This tests the same as private, but also browser settings.

This kind of narrows down the likely cause of either a setting that was changed or an extension you’re using. Both of these are things that can sync across devices depending on what you selected to sync. I mean, it could be some other corruption in the profile itself, but it’s very rare and unlikely.

The headache here is deciding:

  • Settings = Either Reset Settings and see if it resolves. Or compare the settings between old and new profile and make little test adjustments on any changes to see if you can figure out the “specific” setting that fixes it.

  • Extensions = Try disabling to see if it works. Or can just completely remove extensions to remove any hesitation.

None of them are too difficult but can be frustrating depending on the setups. But this would be the next step overall. No guarantees the answer is in either but just seems more likely than anything else at this time.

Removed all extensions and tried to login - Same issue.

Went into setting and selected reset settings and tried to login - Same issue.

Did you think amex may have flagged my profile and that is causing the issue?

@Nickb1907 this is very strange. I know Fanboynz is from Brave and was trying to help, seeing if they or anyone internally can reproduce. His earlier question, it always goes to https://www.americanexpress.com/en-us/account/password/recover?locked=true when you get the error? It would be good if you can confirm that.

I’m going to type out my thoughts here for a moment…

It’s very weird and I’m trying to think what else might be at play. It shouldn’t be able to flag just a browser profile. And if it was blocking Brave itself, I wouldn’t expect it allow you to login on the new browser profile.

And if it was account side, it shouldn’t be letting you login from anything.

Any changes to brave://flags and in custom content filters are the same across profiles, so it wouldn’t be those. Components should also be shared across and have no role. So I wouldn’t look there.

I know if any of the extensions or settings you purged had actually flagged something, the “lockout” cookie could still be in the original profile and needs cleared. Or you would try in private again as if it was the other things it would now work as opposed to before. It’s unlikely but never like to completely dismiss anything either.

You weren’t using VPN or anything during any of these right?

I’m thinking outside the line of checks earlier and my thought by thought here, that’s about the limit of a simple “user side” testing and troubleshooting. At least are the more common things.

Most likely have to defer back to @fanboynz and/or @Mattches to see if they can think of much else.

At least in the interim it seems like you have the other browser profile you can use, assuming that’s still working.,

If the site is specifically checking for Brave, enable shields, ad&trackers.

Add americanexpress.com##+js(brave-fix) in brave://adblock. Visit the main amex page, see if it redirects..

Going to this link brings me to the locked out login screen. As stated previously this is what I get after searching amex and attempting to login. It isn’t a bookmark I am using.

Going into private mode (shields on and off) still get me the locked out screen.

VPN was not in use on both PCs and there isn’t even one installed.

I don’t know what else to check.

I added your link (as shown below) and clicked add. Then tried to login (shields on and off) in normal and private mode and same locked out error.
