**Steps to replicate the issue** (include links if applicable):
* Enable two-factor authentication with a hardware security key
* Enter username/password on mobile web (Pixel 7, Android v15, Chrome 133.0.6943.89)
**What happens?**:
After entering the username and password, I'm briefly sent to the prompt asking me to plug in and tap my security key. Before I'm able to do anything, I'm sent to an error page reading "Authentication process was interrupted. Please start the authentication process again." Tapping "reload" only repeats this issue, until ultimately I get a "too many sign-in attempts" error.
**What should have happened instead?**:
The page should wait for me to plug in my security key and then verify the 2FA.
**Software version** (on `Special:Version` page; skip for WMF-hosted wikis like Wikipedia):
