Thanks for the feedback. The username and password are indeed correct. I copied and pasted from Bitwarden and used the exact same ones to login to the lemmy.ml site. I do wonder if there is some sort of anti-bot measures that Colonel Sanders mentioned below.

Also: I tried just my username vs email but neither worked and I also don't have MFA enabled yet. Super weird.
