Capitalization of email address during login should not matter

[luspi]

Describe the bug
If the email address at login is not written in the exact same way as during sign-up then the login fails. Capitalization should not matter here.

To Reproduce
Steps to reproduce the behavior:

1. Go to 2fauth instance
2. Attempt to login with email address using different capitalization as during sign-up
3. Login fails

Expected behavior
Capitalization should not render the email invalid.

Desktop (please complete the following information):

• OS: Ubuntu 20.04
• 2FAuth version: 2.0.0

Thanks for your report.
This should occur only with SQLite db. Do you confirm it is the db you used?

[luspi]

Yes, this happens with SQLite. I initially tried to use MySQL but ran into an error during install (I'll open another issue for that).
