Authenticator App Support for Two Step Authentication

SendSafely now has enhanced support for our two-step login feature that allows you to use a mobile authenticator app for generating authentication codes. Until now, the option to protect your account using two step authentication has relied exclusively on SMS. With this latest update, you can now use a variety of authenticator apps to generate authentication codes directly on your mobile device using Google Authenticator , Duo Mobile , Authy **or** Windows Phone Authenticator.

Two step authentication is only available for accounts that use a SendSafely username and password, and cannot be used if you log in via Single Sign On or using your Google account. You must also have two-step login using SMS set up a pre-requisite, as it will be used as a back up option if you do not have access to your designated authenticator app.

Existing users can set up an authenticator app by following the steps below:

Authenticator Setup

3 - SMS backup option

Once enabled, you will need to enter an authenticator code every time you log in. If you do not have access to your authenticator app, you can choose to have your two factor authentication code sent to you via SMS instead.

Frequently asked questions

Can I use Google Authenticator with SendSafely?

Yes. SendSafely’s two step login supports authenticator apps such as Google Authenticator, Duo Mobile, and Authy, in addition to SMS codes. Current details are on the Security Overview.

How do I set up an authenticator app for SendSafely two step login?

Go to Account Menu, Edit Profile, then the Login Options tab. Enable two step authentication and confirm your mobile number via SMS, click Set up Authenticator App, scan the barcode with your app, and enter a code from the app plus your SendSafely password to finish.

Why does SendSafely require SMS setup before adding an authenticator app?

As described in this 2019 post, SMS two step login is a prerequisite because it serves as a backup. If you do not have access to your authenticator app at login, you can choose to have the code sent to you by SMS instead.

Can I use two step authentication with SendSafely if I log in with SSO?

No. Two step authentication is only available for accounts that use a SendSafely username and password. It does not apply when you log in through Single Sign-On or with your Google account, which use those providers’ authentication controls.

Can administrators require all users to use two step login?

Yes. Enterprise Administrators can require two step authentication for all password-based users from the Enterprise Console, as explained in Enforcing Two Step Authentication with SendSafely.
