To improve account security, many popular websites have enabled two-step verification/two-factor authentication. You may optionally enable this for your forum account. In addition to your forum password, you will be required to provide a second set of credentials to complete your login. If someone were to obtain your forum password, they would not be able to login without the second set of credentials. To simplify the two-step login, you may register your device(s) as a trusted device for 30 days and you will not be prompted for the second set of credentials when logging in/out of the forum. At any time, you can revoke your trusted device(s). Go here to set up two-step verification. You will be asked for your forum password Select the two-step verification method you would like to use If you select the Verification Code via App option, you will be required to have the 3rd party apps installed. To stop trusting a device or if you need to revoke that trust for other devices, you can do this from the two-step verification setup page.
