What are OAuth? Are they safe?

For everything from picture-editing to entertainment we enter the world of Internet, where several websites provide this services for free of cost and you can perform your task for free of cost.

If you have visited then you would definitely be familiar with this.

These websites in return wants your basic info for various purposes for which you need to sign up every time whenever you visit a new website.

To solve this problem their comes OAuth in which you can use your accounts in other popular websites like facebook, google, etc. to provide them your information to these websites.

when you click on login with for example facebook a new window pops-up which instructs you to login into your facebook account.

After that a screen appears in which facebook wants your permission to grant access to that websites to your information.

When you allow then facebook allows the website to access those information which were permitted by you and you are redirected to that website.

A question arises that whether it is secure or not?

Definitely it is secure in case you are aware about what things you are allowing to that website or app to access.

And it is very helpful because entering all the information every time is a waste of time and OAuth saves a lot of time.

Thats it guys!!!.....Please comment your suggestions below. Thank you.
