Proton Pass vs. LastPass: Which Password Manager Should Your Accounting Firm Trust?
Compare Proton Pass and LastPass for accounting-firm access governance, current controls, incident history, secure migration, and offboarding.
An accounting firm’s password manager should make controlled access practical: the right person can reach the right system, a departing employee loses access, and the firm can recover from a lost device without sharing an administrator’s identity.
Proton Pass and LastPass both offer business password management. The choice should follow a documented security evaluation, not a blanket claim that either product makes the firm compliant.
Proton Pass: current business controls
Proton Pass for Business describes encrypted credential storage, sharing controls, activity visibility, and identity-provider integration. Its plan comparison distinguishes core sharing from Professional features such as SSO, SCIM, activity logs, and enterprise policies.
Test the proposed plan against your identity provider, staff roles, and recovery process. A feature listed on the vendor’s site still needs to work in the configuration your team will use.
LastPass: administration and incident history
LastPass Business describes shared-credential permissions, administration, reporting, and identity integrations. These are useful evaluation areas for firms with multiple teams or an IT provider.
Its history also matters. LastPass’s December 2022 incident notice reported theft of customer vault backups containing encrypted sensitive fields and unencrypted data including website URLs. That incident belongs in vendor diligence and any review of previously exposed credentials.
However, describing URL encryption as merely a future feature is outdated. LastPass’s updated URL-encryption announcement says Phase 2 was complete in September 2025, covering additional URL-related fields. Current improvements do not erase historical exposure; both facts should inform the evaluation.
Compare controls your firm can demonstrate
| Scenario | Acceptance evidence |
|---|---|
| Seasonal staff member joins | Access is limited to assigned clients and systems |
| Employee leaves | Identity access, shared vault access, and active sessions are addressed |
| Administrator loses a device | Recovery works through an approved, documented procedure |
| Shared credential changes | Authorized staff receive the update without insecure copies |
| Access review | An owner can identify unnecessary permissions and remove them |
Where a client system supports named accounts and delegated roles, prefer those over sharing one login. A password manager does not change the software provider’s account-sharing rules.
Plan the rollout carefully
Inventory existing credentials without putting them into ordinary spreadsheets or project notes. Design vault ownership around client and service access, assign accountable administrators, and test with non-production credentials first.
Migration exports can contain readable secrets. Use an approved secure transfer process, limit access, verify imported records, and handle temporary exports according to the firm’s security procedure. Do not leave them in email or shared download folders.
Test supported browsers and phones, MFA, recovery, and offboarding before expanding to the whole team. Document how emergency access works when the usual administrator is unavailable.
Security evidence and purchasing
Request current assurance reports, incident documentation, contractual terms, and plan-specific control details. Review them with the person responsible for the firm’s information-security program. Neither a vendor badge nor MFA availability proves your particular deployment meets every obligation.
Obtain a current quote that includes the required administration features and minimum seats. We are not treating historical prices or the absence of a reported incident as proof of superior security.
