1Password vs Proton Pass vs Bitwarden: Which Is Best?
Picking a password manager mostly comes down to three names: Proton Pass, Bitwarden and 1Password. All three use zero-knowledge, end-to-end encryption, so the real differences are price, what they encrypt beyond the password itself, where they are legally based, and how the apps feel day to day. I went through each vendor’s official pages and the latest independent comparisons to lay out who wins where.
Quick comparison
| Proton Pass | Bitwarden | 1Password | |
|---|---|---|---|
| Free tier | Yes — unlimited logins, 10 hide-my-email aliases | Yes — unlimited passwords & devices | No — 14-day trial only |
| Paid plan | Pass Plus ~$1.99/mo | Premium $1.65/mo ($19.80/yr) | Individual $2.99/mo |
| Open source | Yes | Yes | No |
| Independent audit | Yes (Cure53, 2023) | Yes | Yes |
| Encrypts metadata (URLs, item titles) | Yes | Partial | Partial |
| Jurisdiction | 🇨🇭 Switzerland | 🇺🇸 USA | 🇨🇦 Canada |
| Self-hosting | No | Yes | No |
| Integrated 2FA/TOTP | Pass Plus | Premium | All plans |
| Ecosystem | Mail, VPN, Drive, Calendar | — | Watchtower, Travel Mode |
| Try Proton Pass | Try Bitwarden | Try 1Password |
Pricing and free tier
There is no free lunch with 1Password — it dropped its free plan years ago and now offers only a 14-day trial, with the Individual plan at $2.99/month (annual) and Families at $4.49/month for up to five members.
Bitwarden and Proton Pass both ship a genuinely usable free tier. Bitwarden Free gives you unlimited passwords across unlimited devices and even one-to-one sharing; Premium is just $1.65/month ($19.80/year) and adds an integrated TOTP authenticator, 5 GB of attachments and vault health reports. Proton Pass Free covers unlimited logins, notes and cards on unlimited devices plus 10 hide-my-email aliases; Pass Plus runs about $1.99/month and unlocks unlimited aliases, the built-in 2FA authenticator, secure sharing, Dark Web Monitoring and file attachments.
What this means: if you refuse to pay, Bitwarden and Proton Pass are both real options and 1Password is out. On paid plans all three sit within a dollar or two of each other, so price alone rarely decides it.
Security and encryption
This is where Proton Pass makes its strongest case. Like its rivals it is zero-knowledge, but it also encrypts metadata that some managers leave in the clear — usernames, website URLs, vault names and item titles — under a true zero-access model where Proton cannot read your data even in encrypted form. For anyone who treats which sites they have accounts on as sensitive, that is a meaningful edge.
On transparency the field is closer than the marketing suggests: both Proton Pass and Bitwarden are open source, so anyone can inspect the code, and both are independently audited. Proton Pass was audited by Cure53 in 2023 across its apps, extensions and API, rated “commendable” with all issues fixed bar one platform-limited Android edge case. 1Password is closed source — it is audited and uses AES-256 with a secret-key layer, but you cannot read its code yourself.
What this means: for maximum metadata privacy, Proton Pass leads. For open-source verifiability, Proton Pass and Bitwarden tie; 1Password asks you to trust its audits instead.
Jurisdiction and privacy
Proton Pass is built by the team behind Proton Mail and Proton VPN and operates under Swiss privacy law, generally stronger than the US (Bitwarden) or Canada (1Password). Worth being precise, though: Swiss jurisdiction is not blanket immunity — Swiss courts can still compel limited metadata logging (such as IP and connection timestamps) for a specific account under a targeted, valid order. The encrypted vault contents stay unreadable regardless.
What this means: if legal jurisdiction is part of your threat model, Switzerland is the strongest of the three — just don’t read it as “untouchable.”
Ecosystem and everyday experience
Each tool has a different “extra” that may decide it for you:
- Proton Pass plugs into one account alongside Proton Mail, Drive, Calendar and VPN, with end-to-end encrypted sharing of logins to trusted contacts. If you already live in Proton’s suite, it is the natural fit.
- 1Password remains the polish leader: Watchtower breach alerts, Travel Mode to hide vaults at borders, and the most refined autofill and organization — which is why many teams pay the premium.
- Bitwarden is the only one of the three you can self-host on your own server, the deciding factor for the privacy-and-control crowd.
Which is best — for whom
- Best for privacy maximalists: Proton Pass — metadata encryption, zero-access, Swiss jurisdiction and an open, audited codebase.
- Best value / self-hosting: Bitwarden — a free tier that is genuinely enough, $19.80/year Premium, and self-hosting nobody else offers.
- Best polished experience: 1Password — if you want the smoothest daily driver and Watchtower/Travel Mode and don’t mind paying for it (and closed source).
Bottom line
There is no single winner — there is a best fit. If “who can see my data and under whose laws” matters most to you, Proton Pass is the pick in 2026, and its free tier lets you try that privacy-first model at no cost. If you want maximum value or control, look at Bitwarden; if you want the most refined experience and live in a team, 1Password still earns its price. Decide which of the three trade-offs you care about, then the choice makes itself.
