About Your Cisco Unity Connection PIN and Passwords
You have a PIN to sign in to Cisco Unity Connection by phone. You also have a password to sign in to the Cisco Personal Communications Assistant (PCA) website to access the Connection web tools.
It is a good idea to change the initial PIN and passwords given to you by your Connection administrator.
During first-time enrollment by phone, Connection prompts you to change your initial PIN, but it does not let you change the initial passwords that you use to sign in to the Cisco PCA. You change those passwords in the Messaging Assistant web tool.
A Cisco Unity Connection system can be configured so that you use your computer sign-in password as your Cisco PCA password. If your Connection system is configured this way, you cannot use the Messaging Assistant to change your Cisco PCA password.
You can also change your PIN in the Messaging Assistant, but because you are not required to enter an existing PIN to change it there, take appropriate measures to keep your passwords secure for the Cisco PCA and your external service accounts.
To protect your Connection mailbox from unauthorized access, follow the security guidelines provided by your Connection administrator when you change your PIN and passwords. In general, shorter passwords are easier to use, but longer passwords are more secure, especially when you specify a nontrivial password.
The following table describes the attributes of nontrivial PINs and passwords for Connection:
