Can you externally link a user to their own profile?

I'm running a campaign at the moment to encourage some of our migrated users to log into their profiles and update their settings.

Is it possible to use a generic link that will send users to their own profile page OR will it have to be set up as a mail merge to specifically use the users username in the link? 

For example for our own corporate website, I can use the generic link of www.theiet.org/myaccount which will take a user to their own account area once they've logged in. 

However, on our community I can't seem to identify a generic link that will do that as it always seems to include the users username in the link.

What's the best way of doing this?
