Ah yeah, it's hidden away a little cause they don't call it TOTP and you need to manually copy codes into your settings app. Gonna see if I can set it up on Mac cause that's where I'll actually maybe need it.
Set up should be simpler than needing to manually copy codes into your settings app.
When a QR code is present on screen that resolves to a TOTP seed, an additional context menu option should be present to "Add Verification Code in Passwords" or "Set Up Verification Code" or similar.
