Constantly being locked out from HA, despite using correct password

I have had the “Invalid password” message twice this week, I’m using password manager, so I know the password isn’t wrong.

Luckily I am also logged in on my server, so I can set a new password (set to the same password I’ve always had)… It works for a day, then I get the invalid password message again and I am locked out from that device.

Do we know if anything has changed recently? Im on Core
2026.2.2, running inside the docker container.

Any related entries in the error logs?
