Only you
get in.
Four ways to prove it's you.
A PIN on every account
Every account has a 6-digit PIN. Easy codes like 123456 aren't allowed.
Biometrics
Unlock SIQO with your face or fingerprint, with your PIN as backup.
Passkeys
Sign in and confirm transfers with your face, fingerprint or screen lock. Needs 2FA on first.
Two-factor codes (2FA)
Optional. A 6-digit code from an authenticator app, asked at sign-in and before sensitive actions.
Guessing doesn't pay.
Tries before lock
After 5 wrong login attempts, Support checks it's you before unlocking.
Cool-down on checks
Too many wrong PIN or 2FA codes pause checks for 1 minute.
See every login. End any of them.
See everywhere you're signed in, in Settings › Devices. Log out any session you don't recognise.
Every active session
Device, IP address and last login, with this phone marked.
One-tap logout
End any other session straight away.
Log out from all devices
Sign out everywhere at once.

Can't find what you're looking for?
Our support team can help.
Your PIN is the 6-digit code every account has. A passkey uses your phone's face, fingerprint or screen lock, and is asked first once set up. 2FA adds a code from an authenticator app when you switch it on.
Any standard authenticator app that can scan a QR code.
Each phone holds one SIQO account's passkey at a time. If someone sets up a passkey for their SIQO account on the same phone, yours is removed. Log in as usual, then set up a new one.
Contact SIQO Support through the Help Center as soon as you can. If you can still sign in on another device, go to Settings › Devices and choose Log out from all devices.
Reset it in the app with a one-time verification code. If you're locked out, verified users can be helped back in faster, because we have a trusted way to confirm it's you.
Not to get started. Some features, like selling crypto, need Level 1 verification through Sumsub. Level 1 also raises your limits and makes you eligible for account recovery support.
