Changing password to one that is too long gives no error, but fails

I couldn't find this anywhere, so maybe I'm the only one who uses stupidly long passwords and a pw manager. Is there a password length limit? There's not one stated anywhere near the "Change Password" field: I attempted to change mine to a 64-character alphanumeric password (overkill, I know), and it says: ...but the password is not changed. The new password cannot be used to sign in, while the old one can. A 32-char password works fine, so I'm guessing there's a limit somewhere, but I think there should at least be an error message when it fails.

Thanks for pointing this out Tails, there definitely should be a check to make sure that the pw isn't "too long". I've gone ahead and logged the bug, and we'll fix it when we get a chance. I hope you feel secure enough with a 32-character pw :P
