How change profile URL in browser?

I was try to insert user ID into alias with CB Auto Actions to make adress unique.
But I see ID displayed in profile alias twice (in the frontend).

"Leave User as Automatic and leave Access as Everybody" not help.

In Community Builder backend user managment I can't save user after editing!
Get message: Please enter a valid alphanumeric profile url. Must begin with a letter and contain letters, numbers, and dashes only.

I am not programmer (I am designer) and it is difficult to me make a solution.

I don't understand why Community Builder display user login name in profile alias by default, because it is confidential user information.
In my site many users for login name use their emails that also are confidential user information!

The user id is automatically added when the profile url isn't alias safe.

That's because what you supplied isn't valid. CB Auto Actions does not check when you change the alias field via Field action if it's unique and URL alias safe yet. So whatever you supply via CB Auto Actions it must first be a valid URL alias and second be unique until I've this functionality just built into CB Auto Actions.

Then the easiest solution is to just let the user decide for themselves by allowing them to supply a custom profile url if they want through profile edit or make the field required on registration and you've your solution for future users.

What is confidential is entirely based off the site. Facebook and Google both plaster your name across the web. YouTube uses username. The list continues. It's entirely subjective to the usage. Using Email Address as Username is just bad practice on the users part in general and can't help you there other than adjust the validation of the username field to prevent it from allowing email addresses as username.

The best I can suggest is simply make the Profile URL field required and set it to display on both profile edit and registration. Next create a redirect action that on login checks if their alias is empty and if it is then send them to profile edit to fill it out. The redirect is there for existing users so they know it needs completed.

Thanks for explanation. I will try to use your solution.

But I I still think that must be better if in general configuration you create option to choose url address generating from name field or from username.

Once again thank for excellent support!

The URL needs to be unique. Name is not unique. This leaves username, user id, and email address as those are the only unique and enforced unique values for a user. We may add the option later to let you select what field it uses, but we'll have to implement additional usages to increment the alias (e.g. if 2 people have the same name the second person needs a -2 added at the end).
