Minimum lenght for username of 2?

[psychowood]

Not really a bother (hence the discussion and not an issue :) ), but I'm trying to understand if I'm missing something that drives the limit.

Is there a technical limitation for userid length? I have authelia set up and most of my users are 2 chars, I usually create the same userid on every system (name+surname initials unless there are collisions) that is easier to handle for non technical users.

Users is a default PocketBase collection with internal validations. I don't think there's an easy way to lower the min length below three.
