Best password manager apps for iPhone and Android with a privacy focus
Bitwarden is the best privacy-focused password manager for most people; Proton Pass and KeePass apps suit stricter needs. Audits, price and data compared.
For most people the best privacy-focused password manager is Bitwarden: open source, independently audited, generous free tier and available on iPhone and Android. Proton Pass is the best choice if you want a Swiss provider, and KeePassium (iPhone) or KeePassDX (Android) are best if you want your vault to stay in a file you control.
How we picked these apps
This comparison is based on the store listings, App Store privacy labels, the developers' documentation and the audit pages they publish, not on a lab test of each vault. We weighed these points:
- Zero-knowledge encryption. The vault must be encrypted on your device so the provider cannot read it.
- Transparency. Open source code and audit reports you can actually open count for more than a "trust us" badge.
- Data collected. What the App Store privacy label says about identifiers, analytics and diagnostics.
- Where the data lives. Cloud sync, self-hosting or local files, and the jurisdiction of the company.
- Honest pricing. What is free, what needs a subscription, and whether the free version is usable on a phone.
Facts are current as of October 2026; prices differ by country and store, so check before buying.
The best privacy-focused password managers, ranked
1. Bitwarden: best all-round choice
Bitwarden stores an end-to-end encrypted vault that only your master password can unlock. The code is open source (AGPL-3.0 or the Bitwarden licence) and the company lists its third-party audits with links to the reports, including work by Cure53, IOActive and Mandiant. You can self-host the server, and the free plan covers unlimited passwords across devices. Premium costs 19.80 USD per year on bitwarden.com. The App Store label lists email address and device ID as linked data, plus crash data and name as unlinked.
- Pros: open source, many published audits, excellent free tier, self-hosting, passkey support.
- Cons: US company (an EU data region is available), the interface is functional rather than polished, and it does collect some account data.

2. Proton Pass: best Swiss option
Proton Pass comes from Proton AG in Switzerland, the company behind Proton Mail. It is end-to-end encrypted and open source, and Cure53 published a penetration-test report on the apps and API (2023); Proton describes its audit on its own blog. The free plan includes unlimited logins and passkeys, and paid plans add extras such as built-in two-factor codes and more email aliases. The App Store label lists only crash data and other diagnostics, not linked to you, and the paid Pass Plus plan was 35.90 USD per year in the US App Store at the time of writing.
- Pros: Swiss jurisdiction, open source, audited, very little data collected, email aliases built in.
- Cons: younger than its rivals, fewer advanced sharing features, and the best extras need a paid plan.

3. KeePassium and KeePassDX: best for local control
Both apps open standard KeePass database files, so your vault is a file that you store and sync yourself, for example with your own cloud or a sync tool. KeePassium is the iPhone app; its App Store label says the developer collects no data, and Cure53 published a report on the iOS apps and crypto (2024). It is free with an optional paid Premium upgrade. KeePassDX is the open source Android counterpart, with no account and no built-in cloud.
- Pros: no account, no provider holding your data, open formats, minimal data collection.
- Cons: you handle sync and backups yourself, they are less beginner-friendly, and there is no single app for both iPhone and Android (the vault file works on both).

4. 1Password: most polished, but closed source
1Password offers the smoothest experience and strong sharing features. It uses end-to-end encryption with a secret key in addition to your password, and it lists its third-party security assessments online. However, the apps are not open source, there is no permanent free plan (only a 14-day trial), and its App Store label lists more linked data, including usage data, crash data, coarse location, email, name and identifiers. In the US App Store the individual plan was 47.99 USD per year.
- Pros: polished apps, strong family and team sharing, secret key adds protection.
- Cons: subscription only, closed source, more analytics data collected, Canadian company.

What about Apple Passwords and Google Password Manager?
Both are built into your phone, free, and a big step up from reusing passwords. Apple Passwords is convenient inside the Apple ecosystem, while Google Password Manager is convenient on Android and Chrome. Their drawbacks are lock-in to one platform and less transparency than open source alternatives; if you use iPhone and Android or a Windows PC, a cross-platform manager is more practical.

Tips for using a password manager safely
- Make the master password long. A passphrase of four or more random words beats a short complex password, and you should never reuse it anywhere.
- Turn on two-factor authentication for the manager account itself, preferably with a security key or an authenticator app.
- Keep a recovery plan. Store the emergency kit or recovery code offline, because zero-knowledge providers cannot reset a forgotten master password.
- Use passkeys where offered. They resist phishing, and Bitwarden, Proton Pass and KeePassDX all handle them.
- Lock the app quickly and enable biometrics only if your phone itself is well protected.
Our honest conclusion
Pick Bitwarden if you want one trustworthy, free, cross-platform manager. Pick Proton Pass if a Swiss provider and minimal data collection matter more to you. Pick KeePassium or KeePassDX if you are happy to manage sync yourself in return for full control, and consider 1Password only if you value its polish more than open source. Any of them is far safer than reusing passwords or storing them in a notes app.
Frequently asked questions
Is a password manager safe if the company is hacked?
With zero-knowledge encryption, attackers who steal the server data get only encrypted vaults. The protection depends on a strong master password, which is why we recommend a long passphrase.
Is Bitwarden really free?
Yes, the free plan covers unlimited passwords on unlimited devices. Premium adds extras such as the built-in authenticator, file attachments and emergency access.
Which password manager works offline?
KeePassium and KeePassDX work with a local file and need no internet. Bitwarden, Proton Pass and 1Password keep a cached copy of your vault, but syncing needs a connection.
Should I trust the password manager built into my phone?
It is much better than reusing passwords and is free, but it ties you to one ecosystem. A cross-platform, open source manager gives you more transparency and portability.
What happens if I forget my master password?
With zero-knowledge managers nobody can recover it for you, so keep a recovery code or emergency kit in a safe place offline.
