There is apparently no way to update the password for a given wireless network, so one has to delete the entire network entry and start over.

• Go to Settings → Wi-Fi
• Tap on the i-in-a-circle information icon for the "nasa" network.
• Tap "Forget this network"
• Confirm by tapping the "Forget" button in the white dialog box.
• Tap "< Wi-Fi" to return to main Wi-Fi screen.
• Now set it up again by tapping the "nasa" entry, then entering your username (ndc\your_username) and your password.
• Tap Trust in the upper right of the Certificate window if this is presented to you.

• Go to Settings → "Mail, Contacts, Calendars"
• On the Accounts screen, tap on your NASA NOMAD account.
• On the next screen with the name of the account at the top, e.g., "NASA NOMAD", tap on the line which says "Account" with your email address
• Tap the Password field. There is no way to modify this; you will have to type your password from scratch. Do so now.
• Tap "Done" in the upper right and wait to see checkmarks appear next to every entry.
• If you have an IMAP account, you need to change SMTP separately.
  • Tap on Account again (from "NASA NOMAD" screen)
  • From the Account screen, tap on SMTP (below "Outgoing Mail Server")
  • On SMTP screen, tap on the line below "Primary Server" (probably says "smtp02.ndc.nasa.gov")
  • On the "smtp02.ndc.nasa.gov" screenm, tap the Password field. There is no way to modify this; you will have to type your password from scratch. Do so now.
  • Tap "Done" in the upper right and wait to see checkmarks appear next to every entry.
  • Tap on "< Account"
  • Tap "Done" in the upper right (on the Account screen)
• Tap on "< Mail..." to go back to "Mail, Contacts, and Calendars".
• Tap on "< Settings" to go back to main Settings screen (this is optional).
  You're done.
