![]() ![]() To use TOTP two-factor authentication in ProcessWire, you must be running version 3.0.109 or newer, and you must install the TfaTotp module (link below). However, you may increase security by combining a traditional password with a time-sensitive one-time password (TOTP). But if you were to do that, you'd want to do so very securely, as the more copies of that secret that there are, the less secure it is. Implementations of the TOTP Authentication Protocol. If you are using another application like Google Authenticator, you could always keep your own backup of the QR code/secret, so that you could plug it into any other phone or authentication app and continue to generate codes with it. To start using the TOTP 2FA method in your Namecheap account, go to Profile > Security > Access > Two-Factor Authentication page and click Enable: Enter your Namecheap password and confirm the change by clicking Continue: PLEASE NOTE: If you already have another 2FA method enabled, the pop-up window with a request to confirm the. Applications like Authy and LastPass keep that backup for you (cloud-sync). So this could be a problem, unless you've got a backup of your private key. There is an easy to use client app for both iOS and Android in the form of the Google Authenticator app. It is an open standard with available implementations in multiple programming languages and platforms. What if your phone dies or gets lost? Since the private key (secret) is stored on your phone, you'd no longer have the ability to generate authentication codes. TOTP is commonly used as the second factor in Two Factor Authentication. From that point forward, the website and phone can confirm identity with a 6-digit code that changes every 30 seconds. But you can combine a standard password with a Time-Based One-Time Password (TOTP). When you use your phone and authenticator app to scan a QR code, it is sharing that secret with your phone. TOTP relies upon a long string of characters called a "secret", which is a private key that is stored server-side with the user account when enabling two-factor auth. One of the nice things about TOTP is that all the applications implement the same algorithm (described in RFC 6238), and thus there is likely to be broad compatibility between them. LastPass Authenticator (Android, iOS, Windows, Mac, Linux, cloud-sync).Tip: If you use an account through your work, school, or other group, these steps might not work. Under How you sign in to Google, select 2-Step Verification Get started. Authy (Android, iOS, Windows, Mac, cloud-sync) In the navigation panel, select Security.TOTP is supported by all of these authenticator applications (and likely others), which you can use with ProcessWire: TOTP is implemented by many mobile authenticator applications, and thus widely available and in widespread use. It does this with a shared secret key and the current time. TOTP standards for “Time-based One-Time Password”, which is an algorithm that computes a one-time password. ![]()
