Start on the front page. Tap the avatar in the toolbar.
Tap Edit My Profile
Tap Generate new password.
What happens if I tap Go? Let’s find out. Tap Go.
Form submitted. Profile updated. The iCloud keychain is offering to Update. This could be considered really quick and convenient, or startling. If you don’t use iCloud keychain and instead using 1Password or LastPass, this can catch you unawares. The clipboard did not have a copy of the generated password so I don’t have a way to update the password in 1Password. Anyhow, tap Update Password.
The notice has the generic Profile updated message. Given the anxiety of changing a password, should a message specific to changing the password be shown? Maybe link to password recovery info. Tap the Home icon in the toolbar.
