If you use the Ledger Authenticator application as a second factor of authentication to sign transactions with your Nano or your HW.1, you may experience difficulties to receive your 4 digit notifications.
This issue can happen if:
- You use an iOS phone: the latest updates of iOS do not support this signature. You shall use another mobile phone (Android one) or use the Security card instead of the Ledger Authenticator.
- Your didn't pair your smartphone or the pairing didn't succeed: if so, refer to the Ledger Authenticator guide
