Sending email via gmail:Too many login attempts

[fehernyul]

Hi!

The authentication button works success ( we have to use on the browser the [Go to OAuthTeszt (unsafe)) link. But If we want to send an email ( Send MSG button) we got an error on this line: IdSMTP1.Authenticate; Error message : " GMailAuthDemo.exe raised exception class EIdSMTPReplyError with message 'Too many login attempts, please try again later. b9-20020adfe309000000b0020d0c9c95d3sm2119253wrj.77 - gsmtp"

Check MSG and Check Imap are works well, just the Send MSG wasn't success,

Could you help me?

Thx G.!
