All About 2FA
What is Two-Factor Authentication?
Two-Factor Authentication (2FA) is an additional security layer to your password. With 2FA enabled on your account, you will have to provide your 2FA code when performing certain actions on the app.
How does TOTP work?
Crypto.com is using a Time-based One-time Password (TOTP) for Two-Factor Authentication, it involves generating a temporary, unique one-time 6-digit code* that only works for 30 seconds. To perform any actions that will affect your assets, you will need to enter this code besides the common password.
*Please keep in mind that the code should consist of numbers only.
Which actions on the Crypto.com app can enable 2FA?
Send crypto to other app users
Crypto withdrawal
Fiat withdrawal
Wallet address whitelist
Keep in mind that once the 2FA has been enabled, it becomes mandatory for all transaction types (Crypto or Fiat Withdrawal, Wallet Address Whitelist, Gift Card Purchase, Mobile Airtime, etc.). if you are using an Untrusted Device.
How do I set up 2FA?
Please refer to the step-by-step guide.
Which authenticators should I use?
Providing strong security and a great user experience are always our top priorities and we support various authenticators. There’s a great authenticator app we would like to recommend to you - Authy (Android) / Twilio Authy (iOS).
Authy is not only supporting generating a time-dependent 6-digit code like other authenticators in the market but also offering the following features:
Multiple-device functionality
2FA tokens automatically sync to any new device you authorize. And, if a device is lost, stolen, or retired, you can deauthorize it from any authorized device just as quickly.
Encrypted recovery backups
Authy takes advantage of encrypted backups in the cloud. In case you lose your phone, you can still access Authy (Android) / Twilio Authy (iOS) accounts from other devices
Please note that we are supporting various authenticators, you can still use any other authenticators like Google Authenticator, and you can change to Authy (Android) / Twilio Authy (iOS) at any time.
