A password manager solves a basic security problem: people cannot reliably remember a different strong password for every account. Reuse turns one breached password into a key that attackers can try across email, shops, cloud services and business systems.
Proton Pass combines a password manager with passkey support, encrypted notes and hide-my-email aliases. That makes it both an account-security tool and a way to reduce how widely your real email address spreads.
Quick verdict: Proton Pass Free is unusually complete for individual use, with unlimited logins and devices. Pass Plus is most valuable for integrated 2FA, unlimited aliases, secure sharing, monitoring and emergency access. Existing users of a mature password manager should migrate only if the Proton workflow is genuinely better for them.

What Proton Pass stores
Pass supports:
- usernames and passwords;
- passkeys;
- secure notes;
- payment cards and identities;
- two-factor authentication secrets on paid plans;
- files and shared vault items on supported paid plans;
- hide-my-email aliases that forward to a real inbox.
The vault is end-to-end encrypted. Proton says encryption covers not only password fields but also metadata associated with stored items. Apps are available for major browsers, mobile platforms and desktop operating systems.
The service uses the same Proton Account as Mail, VPN and Drive. That is convenient, but it increases the importance of securing that one account and preserving recovery information.
Why aliases matter
A hide-my-email alias is a unique address used instead of your real inbox. Mail sent to the alias forwards to a chosen mailbox.
Aliases help in three ways:
- A data breach exposes the alias instead of the primary address.
- You can identify which service leaked or misused an address.
- You can disable a spammed alias without replacing the real inbox.
They are not anonymity magic. The website still knows whatever other information you provide, the forwarding service must process delivery, and replying requires correct alias support if you do not want to reveal the underlying address.
Proton Free currently includes ten aliases. Pass Plus and Proton Unlimited include unlimited hide-my-email aliases, subject to fair-use rules.
Passwords, 2FA and passkeys
Unique passwords
Use the generator for long random passwords. Never weaken a generated password merely to make it memorable—the manager exists so you do not need to remember it.
Integrated 2FA
Pass Plus can store time-based one-time password codes and autofill them. This is convenient and still protects against password-only attacks. Keeping the password and 2FA seed in the same vault reduces separation, however.
For high-value accounts, consider a separate authenticator or hardware security key. For ordinary accounts, integrated 2FA is often better than no 2FA because a separate app felt too inconvenient.
Passkeys
Passkeys use public-key cryptography and can resist phishing better than passwords because authentication is bound to the legitimate service. Proton Pass supports storing and using passkeys across devices.
Do not delete every alternative login method immediately. Passkey support, recovery and cross-platform behaviour still differ between services. Test account recovery before relying on a single credential path.
Free versus paid
| Feature | Proton Pass Free | Pass Plus / Unlimited |
|---|---|---|
| Logins, notes and cards | Unlimited | Unlimited |
| Devices | Unlimited | Unlimited |
| Passkeys | Included | Included |
| Hide-my-email aliases | 10 | Unlimited |
| Integrated 2FA | No | Yes |
| Secure item and vault sharing | Limited/basic | Advanced sharing |
| Dark-web monitoring | Basic weak/reused alerts | Expanded monitoring |
| Emergency access | No | Yes |
| Custom domain for aliases | No | Yes on supported paid plan |
Proton promotes Pass Plus, Pass Family and Proton Unlimited. Prices and introductory offers change frequently, so compare the full renewal price. Unlimited is generally the better bundle only when you also want premium Mail, VPN or Drive; otherwise a focused Pass plan avoids paying for unused services.

How to migrate safely
1. Prepare the Proton Account
Create a strong unique account password. Enable the strongest practical MFA and store Proton recovery codes somewhere other than the Pass vault itself. If the vault contains the only route back into the account, a lockout becomes circular.
2. Export the old vault securely
Most password-manager exports are unencrypted CSV or JSON files. Treat the export like a master key:
- create it on a trusted, updated device;
- import it immediately;
- do not upload it to ordinary cloud storage;
- securely remove temporary copies and empty trash afterward;
- retain an encrypted backup only if your recovery plan requires it.
3. Verify before deleting anything
Check a sample from every item type: logins, long notes, URLs, passkeys, cards, custom fields and attachments. Confirm that browser autofill chooses the right login and mobile apps can reach the vault.
4. Run both managers briefly
Keep the former manager read-only for a short transition. Avoid creating new passwords in both vaults or you will lose track of the current version.
5. Fix weak accounts in priority order
Start with the primary email, Proton Account, domain registrar, financial accounts and cloud storage. Replace reused passwords, then enable passkeys or hardware-backed MFA where available.
Sharing without creating a password mess
Never send passwords in email or chat. Use secure item or vault sharing and give access only to people who need it. For teams, make ownership explicit:
- personal accounts stay in personal vaults;
- shared operational credentials go in a controlled shared vault;
- every person gets an individual account;
- remove access during offboarding;
- rotate important shared secrets after membership changes.
A family plan can simplify shared household logins while preserving private individual vaults. Business users should also evaluate administrative controls, audit needs and recovery policies—not just the consumer feature list.
The all-eggs-in-one-basket question
Using Mail and Pass under one Proton Account concentrates trust and recovery. That can be a weakness if the account is poorly protected, but fragmentation is not automatically safer. Five badly managed services can create more attack surface than one well-secured ecosystem.
Reduce concentration risk with:
- a strong account password that exists nowhere else;
- hardware-backed MFA or a well-protected authenticator;
- offline recovery codes;
- a current encrypted vault export;
- separate recovery contact details where appropriate;
- device encryption and screen locking.
Final verdict
Proton Pass gets the fundamentals right and makes email aliases a first-class part of account hygiene. The free plan is enough to build a strong baseline. Plus earns its price when aliases, integrated 2FA, sharing and recovery features replace separate paid tools.
The best password manager is the one you will keep updated, can recover safely and can use on every device. Test Proton Pass with low-risk accounts, verify an export and only then make it the root of your digital security.
