If you no longer have access to the mobile phone number on your account, or the Digidentity app is no longer generating your login codes, it is possible to recover this login detail from the Digidentity login page.
The steps you can follow to do this vary depending on whether you would like to receive your login codes via a mobile phone number (through SMS), or via the Digidentity app (on a smartphone/tablet).
