Looking to set up Two-factor Authentication (2FA)?
Find out how in our step-by-step article.
An authenticator app is usually installed on a smartphone and generates a 6-8 digit code every 30 seconds. The code can be used for signing in, trading, depositing or withdrawing funds from your account or as a Master Key. Note: 2FA for each of these account actions needs to be setup separately.
The secret key provided at the time of download is all that is needed for backup.
Note: authenticator apps are not tied in any way to your SIM card or phone number and that improves security by protecting your account from SIM swapping.
A popular example is Google Authenticator, which can be found in Google Play and the iOS App Store.
Hardware Security Keys are considered to be both more convenient and more secure.
