Brave password manager combines 2 sites

For some reason, the brave password manager combines together 2 site passwords. The sites are part of the same company managed domain. Due to this combination, changing the password on one site and saving it leads to me being unable to autofill the password on the other site. Brave version 1.98.60

This is a well-known Chromium upstream behavior:

The password manager treats all subdomains under the same parent domain as a single site.

There’s an older thread (Manage different logins/passwords for subdomains under the same domain July 2023)

… where the response is essentially:

This is inherited from Chromium; no fork is going to “fix” it; and the workaround is to use a third-party password manager (Bitwarden, 1Password, Proton Pass, etc.) or ensure each subdomain uses a unique username so Brave stores them as separate entries.
