The CIO’s office has good guidelines on updating and managing passwords. If you are at a loss, you can use the command pwgen 10 to produce a big list of random but approximately pronounceable passwords.
Use the command yppasswd. It will ask for your old password, then your new one twice. Note that while you are typing your password, nothing will appear on the screen. If you make a mistake, the backspace key and delete key may not do what you think they do (particularly if you are using ssh from a Windows machine), so just keep going. It will complain that the two passwords don’t match and exit. Run the yppasswd command to try again. It will take up to 15 minutes for this change to be picked up on all the linux hosts.
If your desktop is a Windows machine, use SSH (SecureCRT on Windows) to log onto a unix machine (adhara.biostat.wisc.edu for example) and run the yppasswd command.
Use Enterprise Connect ‘Change Password …’ on a macOS desktop machine to change your Windows and macOS password at the same time.
If you are using a Windows machine as your primary workstation you can change the password by logging in and then holding down the CTRL-ALT-DEL keys simultaneously. Then choose “Change a password” from the pop-up menu. It will then prompt you for the old password and the new one twice. Note changing your password on a Windows workstation will also change it for the Windows servers that you log in to.
If you use any of the Windows Servers (winapp1, winstat1, bcgwts5, bcgwts2…etc) you can change the password by logging into one of them and:
Click on the start menu —->Windows Security (on lower right side)——>Change a password
