Current Behavior

We have our first Engineering team member with email format of [email protected]setting up Coder environment which is done via Google OAuth sign-in with Google. Coder is stripping the dot . character from the username so it becomes firstnamelastname and it appears to be breaking JWT authentication. We worked around this by adding SSH key manually to the Coder instance.

I believe this is related to this code

If there is some sane reason I am missing for stripping the dot character from the username please let me know. Otherwise I would like to submit a PR for this issue.

Expected Behavior

Email domain is stripped so user is created as firstname.lastname

Steps to Reproduce

Provision a user via Google with username format of [email protected]

Environment

• Coder version: 2.18.4
