I ran into the same problem with my lemmy account months ago, not being able to log in there too without a reset. Should stop using 128 as a default lol. Thanks for being on top of it.

Trying to login to piefed.social, gives me Client Error. Code: 400: Message: incorrect_login. Im sure its correct because I logged in on the web app to write this comment with the same info

I made a new account and it worked. So I can only assume it was an issue with this account, maybe because of its 128 character password? I only used 60 characters for the new one. Im not sure.
