For many iPhone users, Apple’s built-in Passwords app is the best place to start. It handles passwords, passkeys, verification codes, autofill and syncing across supported Apple devices. If you also use Windows, Android or other platforms—or want a particular third-party feature—compare dedicated managers such as 1Password, Bitwarden and Proton Pass. The available product documentation supports comparing these four options, but not a tested top-10 ranking.
Which password manager should you use on an iPhone?
Choose based on the devices you use and the features you need, rather than treating every app as interchangeable. Apple Passwords is a practical baseline for someone whose digital life is mostly on Apple devices. A third-party manager may be a better fit if you need broader platform coverage or a feature offered by a particular provider.

iCloud Keychain syncs saved passwords and passkeys among approved Apple devices, including iPhone, iPad, Mac, Apple Watch and Apple Vision Pro. Apple says the credentials are synced without being exposed to Apple. That makes ecosystem fit central: the built-in option is most straightforward when the devices you need are Apple devices. Apple’s iCloud Keychain security overview
Consider a third-party manager if you need to use the same vault beyond Apple’s ecosystem or want a provider-specific feature. Before switching, check support for your other devices and browsers, the plan’s sharing limits, account recovery, export options and current cost. The product pages cited here do not establish every detail of those comparisons.

What each option offers
Apple Passwords with iCloud Keychain
Apple Passwords combines credential management with autofill and support for passkeys and verification codes. Shared groups let you share selected credentials with family or trusted contacts. Apple’s documentation describes syncing across supported Apple devices; it does not establish that the app covers every non-Apple platform or every third-party sharing workflow.
1Password
1Password’s iOS support page explains how to enable autofill on iPhone or iPad so saved logins can be used in apps and websites without opening the 1Password app. It also discusses generated passwords and passkeys. The cited documentation does not establish current pricing, full plan features, family terms or a comparative ranking. About Autofill security in 1Password for iOS

How to enable a third-party password manager for iPhone autofill
Installing an app alone does not make it the iPhone’s selected autofill provider. After installing your chosen manager, enable Password AutoFill and select that provider. Apple describes Password AutoFill as supporting login and account creation in iOS apps and webpages, but individual apps and sites may behave differently. Apple Developer: Password AutoFill

For Proton Pass, follow Proton’s iPhone and iPad setup guide for its documented steps. 1Password also documents its iOS autofill flow in its autofill support article.
How to choose between free and paid plans
Start with the feature you actually need. Proton’s product page describes a free plan with unlimited logins and devices, while listing integrated 2FA and secure sharing among paid features. Bitwarden’s iPhone page describes a free offering, but the cited page does not provide a complete current plan comparison. The available 1Password documentation likewise does not establish current price or plan terms.
Before paying, compare the current plan details for your region and the same billing period. Check how many people can share a vault, which sharing features are included, which devices are supported, and what happens if you stop subscribing. Do not compare a temporary introductory offer with another service’s standard renewal price.

What to check before moving your passwords
- Device coverage: Confirm that the manager supports the phones, computers and browsers you use, especially if you use platforms beyond Apple.
- Autofill and passkeys: Check that the provider supports the sign-in methods you rely on, and enable it as the iPhone’s autofill provider.
- Sharing: If you share credentials with family or colleagues, verify who can access them and which plan includes the sharing feature.
- Portability and recovery: Review how to export your vault and recover account access before making a manager your only copy.
- Security evidence: Read the provider’s security documentation and distinguish its own claims from independent audits or verification. The product pages cited above do not independently establish comparative security.
- Total cost: Compare the same number of users and billing period, including renewal pricing and any features you would otherwise need separately.
