Go to User Personal Details in your user menu, which is the menu you see when you hover over your username at the top right of the site. Two-step Verification is an option under Settings in the lefthand menu.

As it says:
Two-step verification increases the security of your account by requiring you to provide an additional code to complete the login process. If your password is ever compromised, this verification will help prevent unauthorized access to your account.

Here's some general information about two-factor authentication (2FA).

If you usually access DoA from a private computer or your own mobile device, this is a good way to make your account more secure. Someone who logs in from a different computer/device will be prompted for a code, even if they know your password. You can set it so that a computer/device is trusted for 30 days, at which point you will need to generate a new code.

This is not a good choice if you use a shared or public computer to access DoA.

If you'd like to enable two-step verification, you can have the code sent to your phone if you install an app such as Authy or Google Authenticator. This is the more secure option, but if you prefer, you can have the code sent to your registered email address – check your spam folder if you don't see it. You will have 15 minutes to enter the code on DoA.

What to do if you need to access your account from an untrusted computer/device
When you verify your account you will get a list of backup codes. At some point, you may need to access your DoA account from an untrusted device that you don't want to verify. You can use a backup code to access DoA. You may want to write the codes on paper and put them somewhere safe. Each code can only be used once.

If you cannot access your DoA account for any reason, email us at [email protected].
