Should I trim spaces in a password field

Question

Just wondering.

We usually trim a user name in various forms in our ASP.Net application, whats the best practices for password fields.

i.e. should we remove

Answer 1

You can use this to alert user that password include spaces or something like that.

if (/^\s|\s$/.test(password)) {
    //alert('Hey Watchout');
}

Triming password is not a good practice.

Hope this helps.
