Precautions when changing your passphrase

On this page:


Overview

Your IU username and passphrase are used by many services throughout Indiana University, including wireless networks, email accounts, logins, and others. You might also access these services through multiple computers, smartphones, or tablets.

With the growing number of devices and services that use your IU username and passphrase for authentication, you should take precautions when you change your passphrase. Devices or services for which you have saved your old passphrase might attempt to authenticate, and thereby lock you out of your account. Use these guidelines to make your passphrase change as smooth as possible.

Before you change your passphrase

Note:
If you have a laptop that's joined to the ADS domain (so you use your IU username and passphrase to log into the computer itself), it's easiest to change your passphrase while you're on campus. If you need to change your passphrase while you're off campus, for Windows computers, UITS recommends that you make a VPN connection before proceeding.
  1. Close your email clients (for example, Microsoft Outlook, Mail).
  2. Close your UniCom/Skype for Business client, and unplug your UniCom/Skype for Business USB phone.
  3. Close any Outlook connections on your mobile device.
  4. Log out of any programs on your computer, log out of any authenticated IU services (for example, Canvas), and close any open files or folders on the network.
  5. On your mobile device, disconnect from eduroam, IU Secure, or any other IU wireless SSID. If your device has an airplane mode, turning that on will prevent it from reconnecting.

Change your passphrase

If you know your passphrase, follow the instructions in Change your IU passphrase. If you don't know your passphrase, follow the instructions in Reset your IU passphrase.

After you've changed your passphrase

Notes:
  • You will receive email confirmation when you change your passphrase. For group accounts, the account and account owner will receive the message.
  • When you change your IU passphrase, it may take up to 20 minutes for all systems to recognize the new passphrase. UITS recommends waiting 20 minutes before contacting the Support Center if you have trouble logging into IU systems, such as One.IU.
  1. On your mobile device, update the saved passphrase for your email account and reauthenticate to eduroam or IU Secure. Some devices may allow you to update these while in airplane mode. If so, update, and then turn off airplane mode. Otherwise, update shortly after turning airplane mode off. Test your email and web browsing.
  2. If your computer is connected to eduroam or IU Secure, disconnect and reconnect. Reauthenticate with your new passphrase (if you are not prompted for new credentials, you may have to change them manually, through the Control Panel or System Preferences). Test your connection in your web browser.
  3. For computers joined to the ADS domain, the username and passphrase you use to log into the computer itself will usually be cached. If your computer isn't joined to the ADS domain, the following is irrelevant; go on to the next step:
    • For Windows computers, if you're on campus or connected from off campus using VPN, it's not necessary to completely log out or reboot in order for your new passphrase to take effect. After waiting approximately 20 minutes, you may simply lock your workstation, and use your new passphrase to unlock it. This should ensure uninterrupted access to services like Outlook, Skype for Business, file servers, and more. If your new passphrase does not work yet on the lock screen, use your old passphrase and try again later.
    • For Macs, if you're on campus, log out of the computer and log in again with your new passphrase.
    • For Macs off campus, you may need to use your old passphrase to log into your computer until you bring it back to campus, when the new passphrase should work. Note that you will still use the new passphrase to authenticate to IU services.
  4. Open your email client, and log in with your new passphrase. If your client does not prompt you for your passphrase, you may have to change it through the Control Panel or System Preferences.
  5. Open your UniCom/Skype for Business client and reconnect your UniCom/Skype for Business USB phone; if necessary, change your passphrase in your client account settings.
  6. Change your passphrase in any other applications in which you have stored it, either within the applications themselves or through the Control Panel or System Preferences.
  7. If you're running Windows 7, check that the Credential Manager hasn't stored old credentials in the Windows Vault. To do so, from the Control Panel, select Credential Manager. Click the names of any credentials linked to your old passphrase, and then remove them from the vault (click Remove from vault).
  8. Log back into any other IU services.

If you miss one of your stored passphrases on a device or service, you might be locked out of your account; if that's the case, your campus Support Center will be able to assist you.
