Set up two-factor authentication.¶
What is two-factor authentication?¶
Two-factor authentication is an authentication method that combines two of the multiple pieces of information used for authentication to verify identity. Combining multiple authentication factors can reduce the risk of unauthorized access due to account list attacks or information leakage. In Repro, it is possible to configure an authentication method that combines two of the three factors used for authentication: knowledge information and possession information.
Knowledge information
Passwords, secret questions, etc.
Possession information
Mobile phones, hardware tokens, IC cards, etc.
Biometric information
Fingerprints, veins, voice prints, etc.
To enable two-factor authentication, you need to set it up yourself from the account settings page.
