To set up authenticator apps on multiple devices:
You first need to set up two-step verification via your mobile phone number for the authenticator app feature to be available.
A QR code and a secret key are provided. If you have previously set up two-step verification via an authenticator app, turn off the feature and turn it on again to get a new QR code and secret key. You need to use the same QR code or secret key on all your devices.
If you want to set up the feature on your other devices later, save the QR code, for example, by taking a photo, or copy the secret key to your notes.
Security codes change every 30 seconds. You may need to wait for a new security code to be generated in your app that will be valid.
The setup is finished. You can use any of your set up devices to sign in to My Kaspersky.
