The process is simple and guided on screen.
General steps (for all methods):
1. Login to your MarTrust Account
2. When prompted, choose a 2FA method (or go to Settings > Security > Two-Factor Authentication)
3. Follow the on-screen instructions
4. Complete the steps shown
Set up Passkey
Choose Passkey as your 2FA method
If Passkey is available on your device, you’ll be prompted to confirm using your device security (Face ID, fingerprint, or device PIN)
Your passkey is saved securely on your device
Setup is complete — no codes required
If Passkey is not available on your device:
We recommend choosing Authenticator App instead. It provides strong security and works on most devices, even without internet.
Set up Authenticator App
Download an authenticator app if you don’t already have one (e.g. Google Authenticator, Microsoft Authenticator)
In the MarTrust app, choose Authenticator App as your 2FA method
MarTrust app will show you a setup key
Copy this key
Do not share this key with anyone
Open your authenticator app and:
Tap Add
Choose Enter key manually
Paste the key from the MarTrust app
Set the account name to MarTrust Crew Account
Return to the MarTrust app and continue
Enter the 6-digit code generated by the authenticator app
Confirm to finish setup
Set up WhatsApp
Choose WhatsApp as your 2FA method
Confirm your mobile number
You’ll receive a one-time code via WhatsApp
Enter the code to complete setup
Set up SMS
Choose SMS as your 2FA method

You’ll receive a one-time code by text message

Tip:
For the best experience, we recommend setting up more than one 2FA method — for example, using a Passkey as your main method and an Authenticator App as a backup.
When adding an additional 2FA method via Settings, you’ll first be asked to confirm your action using your current (primary) 2FA method.
Once the new method is successfully added, it will become your primary 2FA method. You can continue to keep other methods as backups.
