How do I enable two-step (two factor) authentication?

Cloze provides multiple layers of security around your information, from access-protected data centers, to network and application-level security. We use oAuth when we can. Sensitive information, such as your email, messages, and passwords, is always encrypted. 

We also provide support for 2-factor authentication to further protect your Cloze account. 

Cloze supports two options:

  1. Send a text to message to your phone
  2. Use an authenticator app (like 1Password, Google Authenticator, or Microsoft Authenticator).

1.) Tap on More (...) in the lower right of your screen on mobile (iOS/Android) and lower left on


2.) Tap on Settings


3.) Tap on My Account to expand the section and tap on the Enable button next to 2-step authentication.

1.) Enable with mobile phone number

5.) Enter the security code that Cloze has sent to your mobile number. 

2.) Use an authenticator app

Tap on "Use an authenticator app" and then continue with the setup.
