Steps to reproduce the problem:
1. I have got a forward mail of a Job portal mail from one of my friend. That forward mail contains "Apply Now" option. So when my friend got that mail he can click on that mail and he can directly apply to that job without the need of logging in into the Job portal.

What is the expected behavior?
No

What went wrong?
As he forwarded me that mail and when i clicked on "Apply Now" option, i thought that job portal will ask me for login and then i have to apply. The reason is i have saved login credentials and password of that Job Portal in my Gmail account and it is linked with my Chrome browsers across the different systems. But instead of asking my Login Credentials, that link has proceeded logging in into my friend's credentials. This i found out when i saw the profile details are not mine instead it was my friend's profile details

Did this work before? N/A

Isnt it the Browser's functionality to check the https links which is intended for user or to a particular machine..? Or isnt it a GMAIL's option to nullify the links details which has user related details .?
