Multiple Signup with Single Email Address

I was thinking of writing about it fews  days ago but due to busy schedules  I wasn’t able to do so but today it’s free time !

This was a pretty good way of saving our time rather then creating multiple email accounts for signup in one web or mobile portal. This is a pretty good features of Gmail.
Here, my email account is [email protected] and I want to signup two accounts on any web & mobile application for any reason. So, first I will register with [email protected] and after completing registration, again I will signup with the same email address ( for google ) but different for the rest of the world.
So, my email account [email protected] which is already registered. Now, again,

I will add dot (.) in between my email address, like :

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]

[ And many more  combination ]

These all are same account for gmail but web & mobile apps add as a new email address & singup.

All email sent for those account will hit the original inbox ( [email protected])

This is not considered as a vulnerability or any kind of problem because google doesn’t allow you to register second email account with any dots. And I assure that it doesn’t work with Facebook. And rest of the web ? Like a charm !

So, multiple signup with single email account is possible. ( Only with Gmail) So save your time if you need a multiple account !
