Set up OTP for your online accounts with Locker to create an additional layer of security (2FA) when logging in to your accounts.

What is OTP?

OTP (one-time password) is a common form of two-factor authentication (2FA). It enhances the security of your account as it requires you to provide an OTP every time you try to log in to your account on a new device.

You can use the Locker app on your mobile device or the Locker extension as an authenticator app to log in to accounts you have enabled 2FA. More specifically, Locker can generate, store, and display unique six-digit security codes, which you will need to finish the login process on your online accounts.

Locker Authenticator is only available with websites or services that offer two-step verification processes. To begin setting up 2FA with Locker:

i. Open the websites or services you want to secure with two-step verification.

ii. Go to Account Settings > Security and follow the steps to enable 2FA. This should eventually provide you with a QR code or setup key.

iii. Now you can choose to scan a QR code or enter a setup key to enable 2FA for that account.
