To Check Google's username and password

Question

I have an application where i need to check whether the username and password given as input is google's username and password , then show him some custom settings based on that.

I could not check on the internet as in my office, the Gmail keyword is blocked and when I navigate to other sites, they are blocked because of blocked keywords.

Can anyone guide me? Either PHP or Java is acceptable.

Answer 1

"Oh hello, if you only give me your username and password to google's services, and also your SSN, and CC number and PIN, and your birth date, name and address; I need it all but I won't misuse it, honest."

That's what I hear when someone asks me for my name and password, for an e-mail service no less: what do most password-recovery systems use? Oh, right, your e-mail. The access to which you've just shared with an anonymous stranger. On the Internet. But hey, Facebook also asks for the right to ruffle through your e-mails, and they wouldn't be evil, so no problem, right?

Also, your app now needs to store username+password, as it will essentially become the user, as far as Google is concerned . I trust Google not to leak my name and pass; OTOH I absolutely do not trust you not to leak those (either intentionally, or through an outside hack, or an inside disgruntled employee). I do remember a related question about a similar service logging in as you .

@Pekka is right, if you're trying to use the user's access to Google, you should do this using Google's OpenID endpoint , as it's explicitly made for that situation, yet doesn't give you the control over the user's account. (I'm assuming you are not trying to phish the username and password)

Answer 2

you can use peruse the google documentation for this to get more information about the user, provides he/she grants permission to your site. just like how stackoverflow openid works.

http://code.google.com/apis/accounts/docs/OpenID.html

you should also check: http://code.google.com/p/openid-selector/

如果要对Google服务进行身份验证，请使用OpenID或OAuth 。
