Two Factor Authentication

Enable Two Factor Authentication (2FA) on a Atlas account to require a verification code in addition to the username and password associated with the account. The verification code can be retrieved from a limited number of sources and is typically something an authorized user has physical access to. With 2FA, a compromised username and password does not provide immediate access to the account.

Atlas provides the following sources for 2FA verification codes:

Text Messages (SMS)

When Atlas prompts the user for a verification code, Atlas sends the 6-digit verification code using text (SMS) to the provided phone number.

The cellular carrier’s SMS rates apply.

Automated Voice Calls (US / Canada only)

When Atlas prompts the user for a verification code, Atlas calls the provided phone number. An automated system repeats the 6-digit verification code a total of three times before hanging up.

The cellular carrier’s Voice Call rates apply.

The Google Authenticator application
When Atlas prompts the user for a verification code, the user generates a verification code through Google Authenticator. Requires pairing Google Authenticator to Atlas.

Note

Atlas users who operate within a geographic region with limited cellular service coverage or reliability may encounter delays in receiving the 2FA code via SMS or Voice. Consider using Google Authenticator instead.
