====== Paper OTP Codes ======

//Istruzioni in italiano: [[cn:ccr:aai:doc:2fa:ppr|]]//

As a backup method to the smartphone application, it is possible to print a page with disposable codes.

**These codes must be used one after the other, in the exact order indicated. It is therefore recommended to check or cross out the codes on the sheet when used.
**

When the codes on the sheet are about to run out, immediately proceed with creating a new one. To generate a new sheet, it is necessary to log in with a valid OTP code.
