WordPress admin usernames in DevKinsta are required to use at least 5 characters. However, validation for 4 characters exists: WordPress/ms-functions.php at b59c0f307b131efe7bdf4b0670462019519205fb · WordPress/WordPress · GitHub

Exact.
You can only use 3 characters without any problems but not with kinsta.
So its a feature request? I dont think so

+100! I usually use test/test on all my local-only wp installs. I’d like to expand this to fewer required characters for usernames AND passwords.
