Gapi bad authentication

[GoogleCodeExporter]

Hello
I have a problem with the gapi authentication. I have the following error:
Fatal error: Uncaught exception 'Exception' with message 'GAPI: Failed to 
authenticate user. Error: "Error=BadAuthentication "' in.....
I am sure the login data is correct.
Does anybody knows a solution. 
Thanks in advance

Hello, to stop this error, you must release the google analytics in your 
account by accessing:
Also, in your settings you must create a specific password to be able to 
perform this procedure: https://code.google.com/apis/console/

Enabling "less secure applications" with google helped solve the issue on my 
setup.

done here: 
https://www.google.com/settings/security/lesssecureapps

Why it works???
https://www.google.com/settings/security/lesssecureapps
And
https://accounts.google.com/DisplayUnlockCaptcha

Other people are advised to access the api has been doing through the creation 
of applications in the console:
«Also, in your settings you must create a specific password to be able to 
perform this procedure: https://code.google.com/apis/console/»

What are the differences in these two ways of authorization? 
If authorization works via email and password, why somebody do the 
authorization through the console developers?? Limits? or what?
