fix: Enabling the ability to log in with a username consisting of 2 characters

Description

For now, we have the ability to register with a username consisting of 2 characters. However, when we try to log in with this username, we receive an error indicating that the 'username should be at least 3 characters.' In this PR, we fix this bug.
