Multi-tenant administration is only the starting point. This guide compares how five credential platforms handle vault access, recovery, phishing exposure, and the browser sessions left behind during offboarding.
Vendor documentation reviewed August 24, 2026. Features and packaging can change.
“Not documented” means we could not find an equivalent native capability in the vendor documentation reviewed. It does not mean the product cannot participate in a broader workflow using an IdP, MDM, or another security product.
| Capability | Locke | 1Password | Bitwarden | Keeper | Proton Pass |
|---|---|---|---|---|---|
| Password and passkey management | Yes | Yes | Yes | Yes | Yes |
| Passkey sign-in to its own vault | Yes | Beta | Yes, environment limits | Yes | No |
| Secure inboxes with anonymous email addresses | Native, sender-controlled | Fastmail integration | External integrations | Not native | Native aliases |
| End-to-end encrypted account recovery | Trusted Circle | Recovery code or admin workflow | Enterprise admin recovery | Admin recovery | Phrase or recovery contact |
| Post-quantum protection | Sharing and recovery | Not documented | Not documented | Phased rollout | Roadmap |
| Row-level encrypted spreadsheet | Native | Not native | Not native | Not native | Not native |
| Impersonation detection to stop phishing | Visual checks and Secure Inbox | Domain warnings | URI checks and site blocker | AI and URL checks | Aliases and passkeys |
| Strong Single Logout | Yes | Not documented | Not documented | Not documented | Not documented |
Strong Single Logout clears cookies and site storage from connected browser profiles and reloads open tabs. It is a browser-containment step; it does not replace directory deprovisioning, endpoint response, password rotation, or provider-side session revocation.
Worth evaluating when an MSP wants client-isolated administration plus differentiated recovery, phishing defenses, post-quantum cryptography, and browser-session containment. Locke is a younger platform with a smaller integration ecosystem than established vendors.
Explore Locke for MSPs →A mature choice for MSPs that value broad recognition, a dedicated MSP edition, centralized billing, granular technician access, and an expanding SaaS-management portfolio.
Read the detailed comparison →A strong fit when open source, self-hosting, and a mature Provider Portal are central requirements. Its public documentation also covers SCIM, directory sync, SSO, and detailed enterprise controls.
Read the detailed comparison →Keeper brings mature enterprise administration and is rolling out post-quantum protection in phases. Proton Pass stands out for privacy-focused email aliases. The best fit depends on whether those strengths matter more than MSP-specific operations.
Can technicians move between client tenants without sharing admin credentials?
Who can recover a locked-out employee, and what can that recovery party decrypt?
What happens to organizational and personal data when an employee leaves?
Does offboarding revoke only the vault, or also sessions already active in the browser?
Which features are native, and which require another paid product or integration?
Can you prove tenant isolation, administrative actions, and recovery events to a client?
We compared the documented implementation rather than treating similar category labels as identical. Native features, integrations, beta access, phased rollouts, and product roadmaps are labeled separately. Locke authored this comparison, so buyers should verify short-listed capabilities directly with every vendor.
