Hi @Rick_Sauer
On my server I restrict self-registration and manually create all new user accounts, typically I do this with the command tutor local do createuser --staff --superuser yourusername user@email.com --password SomeRandomComplexPassword (leave out staff/superuser for standard learners) and then have users follow the forgot password link on the login page to apply their own password. This can also be scripted to run in a for loop if you have a massive list of users to create in bulk.
There’s also an API endpoint that can be used to create users, I haven’t actually tried this before though, I’ve just gotten so used to doing the other way
