Security

Protection at every layer.

From the moment you sign in to the moment money leaves your account, multiple safeguards work together to keep you safe.

Two-factor authentication

Protect sign-in with an authenticator app, plus single-use backup codes.

Transaction PIN

Every payment requires your private 4-digit PIN. Five wrong attempts lock payments for 30 minutes.

Step-up verification

Larger payments need an extra one-time code sent to you.

Device management

See every device signed in, where and when — and sign any of them out remotely.

New sign-in alerts

We email you when your account is accessed from a new device, with a one-click “this wasn’t me” lockdown.

Fraud monitoring

Unusual activity — like large payments from a new device — is flagged and reviewed by our team.

Encryption

Card details are encrypted at rest with AES-256 and only revealed after PIN verification.

Session protection

Short-lived sessions with rotating tokens; stolen tokens are detected and revoked automatically.

Account lockout

Repeated failed sign-ins temporarily lock your account and alert you by email.

Report suspicious activity

If you think someone has accessed your account, immediately sign out all devices from Settings → Security, change your password, freeze your cards and contact us. Report phishing emails to [email protected].
