Problem logging into gmail..

[Ian Branch 128]

Hi Team,

Win 11, D11.2, Indy as it came with D11.2.

I am trying to receive emails from GMail so I can process them.

I have the following code..

.....
with POP3 do
    begin
      Host := 'pop.gmail.com';
      Username := 'MyUserName@gmail.com';
      Password := 'MyPassword';
      Port := 995;
      IOHandler := IdSSLIOHandlerSocketOpenSSL;
      UseTLS := utUseImplicitTLS;
    end;
    with IdSSLIOHandlerSocketOpenSSL do
    begin
      Destination := 'pop.gmail.com:995';
      SSLOptions.SSLVersions := [sslvTLSv1, sslvTLSv1_1, sslvTLSv1_2];
      Host := 'pop.gmail.com';
      Port := 995;
      DefaultPort := 0;
    end;
    POP3.Connect;
....

When run and it attempts to connect I get an error. "Username and password not accepted."

I have verified and even reset my gmail password to no avail.

I am clearly missing something, or is it a GMail thing....

Thoughts, suggestions, education appreciated.

Regards & TIA,

Ian

Are you using your gmail password there? That hasn't worked in months.

See https://support.google.com/accounts/answer/6010255

 

You can't use your username and gmail password anymore.

You need to enable 2FA and create and use an App password.

See https://support.google.com/accounts/answer/185833

Tks rvk.  What a PITA.

Would I be correct in assuming that the same thing applies to IMAP??

[rvk 44]

Yes. That includes IMAP access.

 

The complete "Less secure app access" option isn't available anymore.

See https://myaccount.google.com/lesssecureapps

 

And I thought App passwords were only available when you switch on 2FA.

Other option is OAuth2 (which is even more a pain).

FYI, there is a sasl-oauth branch in Indy's GitHub repo to add OAuth2 SASL components for TIdSMTP/TIdPOP3/TIdIMAP4 (and TIdDICT).  You would still have to obtain/refresh the OAuth2 token yourself from Google (or other OAuth2 provider), such as via HTTP, but Indy can then submit the token via SASL when accessing email.
