T-Mobile Sidekick Reference Guide

3 Select a username.
The username you type will become the first part of your email address
(for example, username@example.com). Before you select a username,
read the following:
n Usernames must start with an alphabetic character (A-Z) and can
include numbers (0-9), dashes (-), periods (.), and underscores (_),
but no other punctuation. Although you can use periods within a
username, do not use a period at the beginning or end of the name,
and do not use two periods (..) in a row.
n Usernames must be at least 2 but no more than 32 characters long.
n Usernames are not case-sensitive. For example, if your username is
“bridget”, you will be authenticated if you sign in by typing “Bridget”,
“BRIDGET”, or any combination of upper or lowercase letters.
Once you decide on a username, type it in the text box, then select
Next.
4 Select a password.
Select a secure password that follows the rules below:
n Passwords cannot be the same as your username.
n Passwords must contain 4-15 characters, can include both letters and
numbers, but no spaces, single quotes ('), semicolons (;), backslashes
(\), or percent signs (%).
