Turn Off Auto Suggest Password on iPhone
To turn off auto-suggest passwords on your iPhone, go to Settings > Passwords > Password Options and toggle off AutoFill Passwords. This stops iOS from offering to save or fill passwords, but your existing saved passwords remain in your iCloud Keychain unless you delete them.
What Auto-Suggest Passwords Does
When you create a new account or change a password in Safari or most apps, iOS automatically generates a strong, random password and offers to save it to your iCloud Keychain. This feature is part of the broader AutoFill system that also fills in saved usernames, passwords, and verification codes. It works across your iPhone, iPad, and Mac when you are signed into the same Apple ID.
Auto-suggested passwords are typically 20+ characters long, mix uppercase and lowercase letters, numbers, and symbols, and are unique to each site. This is why they are much harder to crack than passwords most people create themselves. However, some users find the pop-ups intrusive, or they prefer to use a third-party password manager and want to avoid duplicate prompts.
How to Turn It Off (Step by Step)
- Open the Settings app on your iPhone.
- Scroll down and tap Passwords. You may need to authenticate with Face ID, Touch ID, or your passcode.
- Tap Password Options at the top of the screen.
- Toggle off AutoFill Passwords.
That’s it. After this, iOS will no longer offer to save new passwords or fill in saved ones. If you only want to stop the suggestions but still want saved passwords to fill, there is no separate toggle for that—turning off AutoFill disables both saving and filling.
What Happens to Your Saved Passwords?
Disabling AutoFill does not delete your saved passwords. They remain in your iCloud Keychain, encrypted and synced across your devices. You can still view them manually by going to Settings > Passwords and tapping any entry. If you later re-enable AutoFill, your saved passwords will work again as before.
If you want to permanently delete a saved password, go to Settings > Passwords, tap the entry, then tap Delete Password. You can also delete multiple at once by tapping Edit in the top-right corner.
Why You Might Want to Keep It On
Auto-generated passwords are one of the strongest defenses against credential stuffing and password reuse attacks. According to password manager statistics, a large majority of data breaches involve reused passwords. By letting iOS create and store unique passwords for each site, you eliminate the risk of one compromised password giving access to multiple accounts.
If your concern is that you won’t remember the passwords, you don’t need to—iOS stores them securely and fills them automatically. You only need to remember your iPhone passcode or use Face ID/Touch ID to unlock the password list.
Using a Third-Party Password Manager Instead
If you prefer a third-party password manager like 1Password, LastPass, or Bitwarden, you can still use AutoFill but change the source. After installing the app, go to Settings > Passwords > Password Options and under AutoFill Passwords, select the third-party app instead of iCloud Keychain. This way, you get the convenience of AutoFill without using Apple’s built-in password generator.
Note that some third-party managers have their own password generator that can be set as the default. You may need to disable iCloud Keychain AutoFill entirely to avoid conflicting prompts.
Common Problems and Troubleshooting
- AutoFill toggles back on after an iOS update: Occasionally, a system update may reset some settings. Check the toggle again after major iOS updates.
- Passwords still fill in apps: Some apps use their own password fields that bypass the system AutoFill. This is normal and not controlled by this setting.
- Verification codes still autofill: Even with AutoFill off, SMS verification codes may still appear above the keyboard. To disable that, go to Settings > Passwords > Password Options and toggle off Verification Codes.
- Can’t find Password Options: On older iOS versions (before iOS 14), the path is Settings > Passwords & Accounts > AutoFill Passwords.
Frequently Asked Questions
Will turning off AutoFill delete my saved passwords?
No. Your saved passwords remain in iCloud Keychain. They are only deleted if you manually delete them or if you turn off iCloud Keychain entirely (which would remove them from all devices).
Can I turn off only the password suggestions but keep autofill?
No, iOS does not offer separate toggles for saving and filling. Turning off AutoFill Passwords disables both. If you want to keep filling but not see suggestions, you can use a third-party password manager as the AutoFill source, which typically has its own settings for suggesting new passwords.
Why does my iPhone keep suggesting the same password?
This usually happens when you have an existing saved password for that site, and iOS is offering to update it. If you don’t want to change it, tap “Not Now� or dismiss the suggestion. To stop the prompt entirely, you can go to the saved password entry and delete it, but that will remove the password from your keychain.
Does this affect passwords on my Mac or iPad?
No, this setting is per-device. If you turn off AutoFill on your iPhone, your Mac and iPad will still use iCloud Keychain AutoFill unless you turn it off there too. On a Mac, go to System Settings > Passwords > Password Options and uncheck AutoFill.
Is it safe to turn off AutoFill?
It is safe, but it increases the risk of using weaker or reused passwords. If you turn it off, consider using a dedicated password manager or at least a unique password for each important account. The biggest risk is not the feature being off—it’s using the same password across multiple sites.
