Came online on bitcointalk.org after a month just saw new button on otp what it stands for? I've created a account on a temp mail and never gonna get otp sadly. Forum has already a features of getting otp while forgetting passwords but why in normal kept on?
If you have not previously activated the two-factor authentication feature, you can log in by leaving the OTP (One-Time Password) column blank.
The OTP code is not sent via email, but you get it via the Authenticator application.
You can see the guide I made previously regarding using the 2FA feature on Bitcointalk below:
