Proton Pass and RoboForm both show up on every "best password manager for teams" list, and they sit in genuinely different parts of the market. Proton Pass is proton AG's password manager — Swiss-jurisdiction, open-source clients, full enterprise identity at a low per-seat price, with the rest of the Proton suite available as a bundle. RoboForm, by contrast, is old-school form-filler turned cost-effective business password manager, with SSO/SCIM in the base plan and a long-standing closed-source codebase.
This comparison is written for the people actually making the call: founders, IT leads and ops folk at startups, agencies and small teams. No affiliate rankings, no "best of" filler — just the trade-offs that matter once more than one person touches the vault.
Quick verdict
Pick Proton Pass if privacy-conscious teams or anyone already on the proton ecosystem. Open-source clients, Swiss jurisdiction, SSO + SCIM at $4.49/user. Server stays closed.
Pick RoboForm if teams that fill a lot of complex web forms and want sso/scim cheap. Cheap Business plan with SSO + SCIM included. Dated UI, closed source, mobile CVEs to track.
Both are zero-knowledge and both have a defensible recent security story. The choice is almost never about cryptography — it's about collaboration model, governance, and how much per seat per month you want to spend.

Pricing for teams: where the real difference is
Pass Essentials is $1.99/user/month (min 3 users), Professional adds SSO/SCIM/audit logs at $4.49/user. Workspace Standard at $12.99/user bundles Mail, Drive, Calendar, VPN and Pass Professional — competitive if you'd buy any of those anyway.
RoboForm Business is $3.33/user/month with no published minimum, and SSO + SCIM are included rather than add-ons. Enterprise is custom-priced and unlocks the self-hosting option (gated to 1,000+ users).
For a fast-growing team, the slope matters as much as the starting price. Model it at the size you actually expect to be in 12 months — not the size you are today.
How teams actually share credentials
Proton Pass. Vault sharing (with any Proton account), per-item sharing via individual item keys, secure links and group sharing on Professional. No anonymous external sharing — recipients must have a Proton account.
RoboForm. Shared folders with three permission tiers (Full / Login-only / Read-only) plus group sharing on Business. The Login-only role is genuinely useful for contractor access; external sharing still requires the recipient to be a RoboForm user.
The everyday question is: when a contractor joins on Monday and leaves on Friday, how much work is it to give them access to exactly the credentials they need, watch what they touched, and revoke cleanly? That's where the daylight between these two shows up.
Security architecture
Proton Pass. All client code is open source under GPL-3.0 with per-item AES-256-GCM keys and bcrypt + SRP for user authentication. Two published audits (Cure53 2023, Recurity Labs 2026) and Swiss-jurisdiction hosting underpin the trust story; the server stays closed source.
RoboForm. AES-256 with PBKDF2-SHA256 at 1,000,000 iterations and a documented zero-knowledge architecture. Two recent Secfault Security pentests (2023, 2025). The pre-2015 generator PRNG flaw and the 2025–26 Android CVEs are worth knowing about even though no vault has been breached.
If you're forced to choose on cryptography alone, modern AEAD ciphers (AES-GCM, XChaCha20-Poly1305) paired with a memory-hard KDF (Argon2id) are the bar. Both vendors are inside that range; the harder differences are open-source posture, audit history, and whether you can self-host.
Admin & governance for teams
Both products support some flavour of role-based access, forgotten-password recovery, and audit logging on the right tier. Where they diverge is on the boring-but-critical stuff: SSO, SCIM provisioning, and whether group policies can keep up with how your team actually grows.
SSO tier: Proton Pass — Pass Professional (SAML); RoboForm — Business (OIDC). SCIM tier: Proton Pass — Pass Professional (Okta, Entra ID); RoboForm — Business.
If Okta, Entra ID or Google Workspace SSO is non-negotiable from day one, factor the tier price into the per-seat number — it's often the thing that flips the cheaper-on-paper option into the more expensive real-world bill.
Proton Pass
Pros
- All client code open source under GPL-3.0
- Encrypts metadata (URLs, usernames, notes) — not just passwords
- SSO + SCIM at $4.49/user, well below Bitwarden Enterprise
- Swiss jurisdiction and strong privacy posture; bundled with Mail/VPN on Workspace plans
Cons
- Server is closed source — no self-hosting
- Vault-level permission model is less granular than 1Password
- External sharing requires recipient to have a Proton account
- Newer product (launched 2023) — smaller enterprise case-study base
RoboForm
Pros
- Industry-leading form-filling (the original differentiator since 1999)
- SSO + SCIM included in the base Business plan
- "Login-only" permission lets contractors auth without seeing the password
- Self-hosting option exists (Enterprise, 1,000+ users)
Cons
- Closed source; no public SOC 2 report
- UI feels legacy compared to Bitwarden or 1Password
- Pre-2015 PRNG flaw in the password generator (long fixed but reputationally notable)
- Two Android-specific CVEs in 2025–26 hint at mobile-hardening lag
A third option worth considering
Proton Pass and RoboForm have very different stories, but they share a UX vintage that shows. Pwdly is a recent build from a small team, so the interface, the sharing flows, and the admin views all assume a 2026 user — not a 2014 one — without giving up on the security fundamentals either product was originally praised for.
- Per-project vaults. Most teams don't share "everything with everyone" — they share by client, repo or product. Pwdly makes that the primary unit, not an afterthought folder.
- $2/user/month, flat. No seat-count cliff, no SSO upsell on the cheapest paid plan. See the full pricing.
- XChaCha20-Poly1305 + Argon2id under the hood. The cipher explainer walks through why those defaults matter.
- Trade-offs we own. No breach monitoring (we literally can't read your data), no self-hosting yet, no browser extension on day one. The security page has the honest list.
If the choice between Proton Pass and RoboForm comes down to "which one will my team actually complain less about", Pwdly is the third sample worth taking.
Frequently asked questions
Is Proton Pass or RoboForm better for a small team?
Proton Pass fits best when privacy-conscious teams or anyone already on the proton ecosystem, while RoboForm is the stronger choice when teams that fill a lot of complex web forms and want sso/scim cheap. Model both at the seat count you expect in 12 months — the cheaper option at 5 seats isn't always the cheaper option at 25.
Which has stronger encryption — Proton Pass or RoboForm?
Proton Pass uses AES-256-GCM (per-item keys) with bcrypt + SRP (Argon2 for local cache). RoboForm uses AES-256-CBC with PBKDF2-SHA256 (1,000,000 iterations). Both are zero-knowledge. In practice the cipher choice is rarely the differentiator — KDF (Argon2id vs PBKDF2), open-source clients, and audit history matter more.
Does either support SSO and SCIM on the cheapest team plan?
Proton Pass: SSO Pass Professional (SAML), SCIM Pass Professional (Okta, Entra ID). RoboForm: SSO Business (OIDC), SCIM Business. If SSO is non-negotiable, price it on the tier that includes it, not the entry tier.
Has either vendor had a vault breach?
Proton Pass: No customer vault breach. RoboForm: No vault breach; pre-2015 PRNG flaw in generator; Android CVEs in 2025–26. A clean record isn't a guarantee, but a known prior incident materially raises the cost of trust.
