Is there a way to have two aliases to a user's profile page?
Assuming you don't want to manually maintaing the second alias - since pathauto only allows you to generate a single automatic alias - then perhaps the easiest way is to use Rules, instead of pathauto. It's been a few years since I did this, and it was for node aliases, not user page aliases, but I don't see why it wouldn't work.


Setup a Rule with multiple steps to create the aliases you need - you can use all the same token substitutions in Rules as you can in pathauto
Run the rule when a user is created
