If you’ve been using Safari for a while on your iPhone or iPad, you’ve probably had it offer to save passwords and credit numbers for you on more than one occasion. If you’re wondering where all of this information goes, look no further than the Safari section in your iOS Settings app. Under the “Passwords and Autofill” subsection, you’ll see categories for “Saved Passwords” and “Saved Credit Cards.”
If you’ve passcode-protected your device (and if you’re storing passwords and credit cards on it, we’re really hoping you have), you’ll need to enter your passcode to get into either of these sections, but once there, you can see a list of all of the passwords and credit card numbers that have been saved for autofilling on web sites, and you can even edit or delete any of them from here. If you’re using iCloud Keychain, these will also sync to your other iOS devices and your Mac, so any changes you make here will be reflected on your other devices. You can also toggle either category OFF from here if you no longer want to be prompted to save or automatically fill in passwords or credit cards when browsing in Safari. A “Use Contact Info” option is also here that allows you to fill in email, name, and address fields on web forms with information from a selected contact record.
As an additional tip, if you’re looking for a quick way to erase all of this data from your iPhone or iPad in one fell swoop, simply go to your “Passcode” section in the Settings app and turn off your passcode entirely — as a security precaution, you’ll be asked whether you want to erase all saved passwords and credit card data. If you’re using iCloud Keychain, this will also toggle that feature off before removing them from your device, leaving them in iCloud, but wiping them from local storage.
