I created a new account and a few new characters to grind for fun, so I created them without passwords.

I eventually decided to go all in with them and use them as my main. I then used the "changepassword" command to set a password on the characters.

This completely broke the login, as they now require a password, but there is no password field on the character selection menu.

I tried to log in with pressing "space and enter" as someone suggested, no luck. I also tried creating another character on the same account WITH a password, to see if the password field popped up then, still no luck.
