Yes. We use:

  • TLS 1.2/1.3 everywhere — no unencrypted traffic.
  • Passwords hashed with Argon2id — even Openline cannot read your password.
  • Two-factor authentication (2FA) available via authenticator app or email OTP.
  • Session tokens rotated on sign-in, sign-out, and password change.
  • Rate limiting on sign-in attempts.
  • Bug bounty with responsible-disclosure guidelines at openline.com/security.

If you notice suspicious activity on your account, change your password and email ask@openline.com immediately.

Still stuck?

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
