Setting up Two-Factor Authentication (2FA) – Cryptal - Support

Two-factor authentication is a security measure used to assure account activity is legitimate and authorized. Cryptal can use E-mail or Google Authenticator to provide one-time passcodes.

	For e-mail authentication, the system will e-mail you a code every time you login.
	E-mail authentication will be enabled by default if no other method is selected
	To use Google Authenticator, download the app to your phone.
	Scan the QR code into the app or enter the text code displayed → You may need this code to restore your account if you lose your phone or delete the Google Authenticator app, so store it somewhere safely. To enable Google Authenticator on your account, enter your login password and then enter the temporary Google Authentication code. Each Google Authenticator code is valid for 30 seconds, so only use a code while it is displayed. Otherwise, just use the next generated code. To change your Google Authenticator device, you must first enable e-mail authentication. This will disable the current Google Authenticator device. Then you can re-enable Google Authenticator with your new device.
