Quick Answer
Proton Pass: best for privacy-first users and Proton ecosystem fans
Bitwarden: best free and open-source option, self-hosting possible, power features
1Password: best polish, families, and business use — but closed source and Mac-only
LastPass: still usable, but past breach means I no longer recommend it
How they compare in 2026
Security & privacy
- Proton Pass uses strong end-to-end encryption, is open source, and run by the Swiss, privacy-focused Proton Foundation, with no known vault breaches.
- Bitwarden is fully open source, independently audited, supports Argon2 key derivation, and also has no known vault breaches.
- 1Password is closed source but has a solid security track record (over 20 years without a vault breach) and uses a unique “Secret Key” in addition to your master password.
- LastPass suffered a major breach in 2022 that led to encrypted vault data being stolen and later linked to large crypto thefts. Though the product continues, that history is a serious red flag.
Open source, self‑hosting, and ownership
- Proton Pass and Bitwarden are both open source, which lets the security community inspect their code.
- 1Password and LastPass are fully cloud-hosted and closed source, so you’re trusting the vendor more.
- Only Bitwarden offers self‑hosting, which is valuable if you want full control over your data and infrastructure.
Features & usability
Proton Pass
- Clean, modern interface, good passkey support, built‑in email aliases via SimpleLogin (hide‑my‑email).
- Good cross-platform apps and browser extensions. Sightly newer and less polished than 1Password on some edges.
Bitwarden
- Very configurable password generator, strong autofill flexibility, good vault organization, and a built‑in two-factor authenticator.
- Interface is more “utilitarian” — mobile and UI require a few more taps vs Proton Pass or 1Password.
1Password
- Best‑in‑class user experience, especially for families and teams.
- Features like Watchtower security dashboard and excellent passkey management.
- Great cross‑platform consistency, but closed source and no built‑in email aliasing.
LastPass
- Decent feature set and familiar UI, but feels dated and carries the baggage of its 2022 breach and ongoing fallout.
