A one-time password (OTP) is a password valid for only one authentication session. It is also usually limited to a certain period of time.
The advantage of a one-time password over a static one is that each OTP can be used just one time.
We strongly recommend you to set it as an additional security feature to your static password.
In this case even if your static password is stolen, the hacker won't be able to log into your personal account without getting an OTP from your smartphone.
To use the feature you will need:
- a smartphone,
- access to internet,
- a Google Authenticator app installed on your smartphone (download here for iOS or for Android)
