Free Proton Authenticator
What is Two-factor authentication – 2Fa?
Two-factor authentication (2FA) adds an extra layer of security to your login accounts, in addition to your password. Even if hackers know your password, they can’t access your account without this second code. An authenticator app generates one-time codes right on your device — safer and quicker than having codes sent by email or SMS.
What is an authenticator app?
An authenticator app is a mobile, desktop, or web-based application that generates time-sensitive, one-time codes to verify your identity, enhancing security for online accounts by providing an extra layer of protection beyond a password.
Proton Authenticator is an open-source and end-to-end encrypted 2FA app that’s simple and free to use. It is available on all platforms, including desktop. Easily sync or back up your 2FA codes so you never lose access to your accounts.
Proton Authenticator is available on every type of device, allowing you to securely sync and back up your 2FA codes with ease.
Create a Proton Mail account first (optional)
To use the free Proton Authenticator, I recommend setting up a Proton Mail account first. A Proton Mail account is great to have, even without the authenticator feature, because it provides a secure backup email address. Proton Mail’s free plan is supported by paid subscriptions that offer extra features and storage. A Proton Mail account is required to sync Proton Authenticator across multiple devices.
Create a free Proton Mail account. Remember, this password will be used for security purposes, so you want a high-quality, unique password, just like the ones you use with your password manager.
Proton Mai is the only email service with Built-in encryption, protected by Swiss privacy laws. It includes email aliases, Advanced security features, a Calendar, a password manager, file storage, and a VPN.
