2FA: What to Expect

TUIO may ask for an email verification code when you sign in. Retrieve the code from the email address shown and enter it to continue.

Trusted devices

If the sign-in screen offers a trusted-device option, use it only on a device you control. A trusted device can reduce repeated verification prompts until its trust expires or is removed. Follow the period and instructions shown during sign-in.

A new device or an expired trusted-device entry can require verification again. The trusted period follows your account's security settings.

Manage your settings

Open your profile menu, select Account settings, then use Manage beside 2-Step Verification or Trusted Devices. See how to manage your 2FA settings.

If you cannot access the verification email or complete sign-in, contact support@tuiopay.com.
