Strip4bit is an adult site allowing users to create account with Trezor and login privately in a secure way without ever needing email or password.
Trezor user manual
When you are on the site, just select Sing in/up button.
Creating a new account and logging into existing one works the same: just click on Sign in with Trezor.
You will be asked to confirm the action on your Trezor and to authenticate with your PIN. Note, that PIN is never asked again until you disconnect the device.
And that's it! You are now logged into your account - no email or password needed.
