Two-Factor Authentication

Missed SMS Authentication Tokens

Use Authenticator Apps When Possible

Authenticator applications are the preferred method to SMS for two-factor authentication. SMS is an older protocol with many known security vulnerabilities. The U.S. NIST advised abandoning SMS for 2FA in section 5.1.3.2 of its Digital Identity Guidelines.

If are using SMS, but do not receive the authentication tokens via SMS:

1. Refer to the Manage Your Two-Factor Authentication Options page for more details about using two-factor authentication. This page includes any limitations which may affect SMS delivery times.

2. Enter the SMS phone number with country code first followed by the area code and the phone number.

   If you are outside of the United States or Canada, include 011 and the country code because Cloud Manager uses the U.S.-based Twilio to send text messages. As an alternative to your non-U.S. telephone number, use a Google Voice telephone number.

   Example

   For New Zealand enter 01164 before the phone number.

   If you do not receive the authentication token in a reasonable amount of time contact Support to rule out SMS message delivery delays.

Delete or Reset Two-Factor Authentication

To delete or reset two-factor authentication, go to https://account.mongodb.com/account/reset/mfa/cloud. The reset button deletes your existing two-factor authentication settings and provides the option to create new ones.

Restore Lost Access to Organizations and Projects

If you created your Cloud Manager account using a Gmail or Google Apps account, the following can cause you to lose access to your organizations and projects:

• The Google email address with which you signed up differs from the email address associated to your account. This is most often the case with Gmail or Google Apps aliases.
• Your username or email domain has changed in Google Apps.

To re-gain access to your organizations and projects:

• Ask a user with the Organization Owner to invite you to the organization to which you lost access, or
• Contact MongoDB Support.
