The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

L'errore *... Autenticazione fallita ...* o *... AUTHENTICATE fallito ...* potrebbe significare che il tuo nome utente o la tua password siano scorretti. Alcuni provider prevedono come nome utente solo il *nome utente* e altri il tuo indirizzo email completo *username@example.com*. Quando copi/incolli per inserire un nome utente o una password, potrebbero essere copiati i caratteri invisibili, che potrebbero anche causare questo problema. Anche alcuni gestori di password sono noti per farlo in modo scorretto. Il nome utente potrebbe essere sensibile alle maiuscole, quindi prova con soli caratteri minuscoli. La password è quasi sempre sensibile alle maiuscole. Alcuni provider richiedono l'uso di una password dell'app invece di quella del profilo, quindi sei pregato di controllare la documentazione del provider. A volte è necessario abilitare l'accesso esterno (IMAP/SMTP) sul sito web del provider prima. Altre cause possibili sono che il profilo è bloccato o che l'accesso è stato limitato amministrativamente in qualche modo, per esempio consentendo di accedere solo da certe reti / indirizzi IP.

Molte reti Wi-Fi pubbliche bloccano le email in uscita per prevenire lo spam. A volte puoi risolverlo usando un'altra porta SMTP. Vedi la documentazione del provider per i numeri di porta utilizzabili.
Many public Wi-Fi networks block outgoing email to prevent spam. Sometimes you can workaround this by using another SMTP port. See the documentation of the provider for the usable port numbers.
Se stai usando una [VPN](https://en.wikipedia.org/wiki/Virtual_private_network), il provider della VPN potrebbe bloccare la connessione perché prova troppo aggressivamente a prevenire lo spam. Nota che anche [Google Fi](https://fi.google.com/) sta usando una VPN.

L'autorizzazione della configurazione dei profili di Gmail con la procedura guidata rapida devono essere ricaricati periodicamente tramite il [gestore del profilo Android](https://developer.android.com/reference/android/accounts/AccountManager). Questo richiede i permessi di contatto/profilo e connettività internet.
The authorization of Gmail accounts setup with the quick wizard needs to be periodically refreshed via the [Android account manager](https://developer.android.com/reference/android/accounts/AccountManager). This requires contact/account permissions and internet connectivity.
L'errore *... Autenticazione fallita ... Profilo non trovato ...* significa che un profilo di Gmail precedentemente autorizzato è stato rimosso dal dispositivo.
The error *... Autenticazione fallita ... Account not found ...* means that a previously authorized Gmail account was removed from the device.

L'errore *... Authentication failed ... network error ...* means that the Android account manager was not able to refresh the authorization of a Gmail account due to problems with the internet connection
L'errore *... Autenticazione fallita ... Credenziali non valide ...* potrebbe essere causato dal cambiamento della password del profilo o avendo revocati i permessi di profilo/contatti necessari. Nel caso in cui la password del profilo fosse cambiata, dovrai autenticare di nuovo le impostazioni del profilo di Android. Nel caso in cui fossero stati revocati i permessi, puoi avviare la procedura guidata di configurazione rapida di Gmail per garantire di nuovo i permessi richiesti (non devi riconfigurare il profilo).
The error *... Authentication failed ... Invalid credentials ...* could be caused by changing the account password or by having revoked the required account/contacts permissions. In case the account password was changed, you'll need to authenticate the Google account in the Android account settings again. In case the permissions were revoked, you can start the Gmail quick setup wizard to grant the required permissions again (you don't need to setup the account again).

The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.
