Hi, how can we help?

Kiren is a digital safety app for iPhone and Android. It helps tell what is real from what is fake: it checks whether an online shop can be trusted before money changes hands, spots deepfakes and manipulated images used in scams, filters harmful messages, and keeps watch over personal information, raising a warning the moment any of it appears in a data breach.

Yes. On the phone's home screen the app icon is labeled F‑Secure Kiren, on both iPhone and Android. Android's app settings and notification settings show the same name. Inside the app, the name is Kiren.

No. Kiren signs in with an email address only. A 6-digit one-time code is sent to that address, and entering the code completes the sign-in. There is no password to create or remember. See Getting Started.

When a subscription has already been purchased, sign in with the email address used for the purchase. The subscription is tied to that address and will not appear when signing in with a different one. A new user can choose any email address. The only requirement is access to that inbox, because the 6-digit sign-in code is sent there.

First check the junk or spam folder, as the message is sometimes delivered there. When signing in on the same phone that receives the email, and email notifications are turned on, the code often appears as a suggestion just above the keyboard, where a single tap enters it. To paste instead, copy the code from the email, return to Kiren, and tap the first number box. The full code drops into place automatically.

If the email still has not arrived once the 30-second countdown on the code screen finishes, the prompt "Haven't got the email? Click here to resend." appears. Tapping it returns to the email screen, where the address can be checked and a new code requested. Requesting a code again for the same address within about half a minute shows "We already sent you a code a moment ago. Check your inbox, or wait to request a new one." The code already sent still works.
