Short Story: I'm a Newbie in application security. I need to implement a login via email.

Long Story: I have built a basic web chat application using SignalR, now i'm working in saving conversation in SQLServer Db. But my next challenge is to create a chat invitation email that will be send to all users from my db. The email should contain a link that when users will click they will be redirected to the chat web-page and automatically signed in.

My question is: Can it be done? And if it can, how can it be done

Thank you for your help!

Just an idea, hence why it is a comment and not an answer but:

Why don't you generate a guid for each user when you click "Send invite", this guid is saved in a table along with with an expiration time.
Then your link you send could be something like
"http://MyChat.Website.Com/Invite/{guid here}"
This calls an action that performs the sign in based on a look up, a) checking the id is valid and b) it has a user associated with it. If successful, that is authentication done. If not it redirects to a "Link expired" page

Actually I would suggest this as a solution. You don't have to write all the code for them but the idea is a solution.

Do not post the same question in multiple places on the same site.
