If you go to the 2FAS page for the first time, you need to create a 2FAS account or log in to the existing one. To create a new 2FAS account, simply press the Sign Up button. If you want to change your e-mail address before creating a new account, feel free to do it. Additional account activation is not necessary. You get an e-mail, but you do not need to do anything to activate your account.
If you have previously created a 2FAS account, you do not need to create a new one. When you are on the Create Account page, just follow the Log in to existing account link, enter your e-mail and password and then press the Log In button.
When you create a new account, or log in to the existing one a new integration is created. Virtually, there is only one difference between these two things. When you create a new account, you cannot use the e-mail address that was used to create an account previously.
You can find all your integrations on the 2FAS dashboard.
If you have never set your 2FAS password or just forgot it, follow the Reset password link on the Logging in to the existing account page. Then make sure the e-mail is correct and press the Reset Password button.
You will get an e-mail with a link to reset your password. If you click it, you can set your new password.
You can choose between two plans: basic and premium. Basic is a default plan. In order to change the plan to premium, firstly press the ADD CREDIT CARD button. You will be redirected to the 2FAS dashboard where you will be able to set up your credit card. If you go back to WordPress dashboard, press the UPGRADE NOW button.
When you are on the 2FAS - Admin page on the WordPress dashboard, you can see a link at the bottom of the page which allows you to log out from your account. Use it wisely. When you click it, a 2FAS plugin removes all its data from the WordPress database. A plugin will be still installed but you will not be able to return to the previous configuration. Even when you log in to your account again, a new integration is being created.
