This feature allows you to log in to TrustLogin using a password sent to your email address, in addition to your regular ID and password. Two-factor authentication enhances security.

This is a separate subscription from the existing One-Time Password (OTP) feature, and the two can be used together.
When used together with OTP, MOTP authentication occurs after OTP authentication is completed.

Note: To use this feature, you need a TrustLogin Pro Plan or option subscription. For pricing, click here
