Description:
This error occurs when you try to log in via the command line
example: mysql -u root -p
and enter a password longer than 79.

I have found the exact line for you:
https://github.com/MariaDB/server/blob/11.0/mysys/get_password.c#L178

I found a user with the same problem:

How to repeat:
You are not able to administer your server or log in to your localhost user.
