Bottom Line: Proton Pass takes the trust Proton earned with encrypted email and pours it into a password manager that is genuinely good — not just ideologically pure. The free tier is absurdly generous, hide-my-email aliases are the killer feature, and the only thing holding it back is the polish gap between a young app and the 15-year veterans it's chasing.
The Free Tier Is the Argument
Let's start where Proton starts: money, or the lack of it. The free tier covers unlimited logins across unlimited devices. Read that again, because it's not the industry norm. LastPass gutted its free tier years ago by limiting you to one device type. Proton does the opposite — it hands you the core product with no device tax and throws in hide-my-email aliases on top.
This is a strategic weapon, not charity. Proton knows that once your entire credential library lives in its vault, you're not leaving. The free tier is the hook, and it's a sharp one. For the average person who just wants to stop reusing "Password123!" across 40 sites, the free tier is not a lite version — it's the whole meal.
Aliases Change the Threat Model
Most password managers protect the password. Proton Pass protects the email address, too, and that's a smarter target. Your email is the master key to your digital life — it's the reset link for every account you own. Every time you hand it to a sketchy retailer, you're widening your attack surface.
Hide-my-email aliases flip this. Each signup gets a unique, randomly generated address that forwards to your real inbox. Sign up for a newsletter, get a throwaway alias. That retailer gets breached? You disable one alias and the damage is contained — the attackers got an address that leads nowhere. Spam floods in? Kill the alias. This isn't a novelty; it's a genuine shift in how you think about online exposure, and it's the single best reason to pick Proton over a pure password vault.
The 2FA-in-the-Vault Debate
Proton bakes a TOTP authenticator directly into the app, so your two-factor codes sit next to your passwords. It's convenient — no fumbling between apps mid-login. But it deserves an asterisk. Purists will (correctly) point out that storing your password and your second factor in the same vault collapses two security layers into one. If someone breaches the vault, they have both.
For most people, the convenience wins and the risk is theoretical — the vault's encryption is the real gate. But it's a design choice, not an unambiguous feature, and Proton doesn't force it on you. Use it or don't.
Where the Polish Runs Thin
The autofill is where the veteran gap shows. On desktop browser extensions it's reliable, but on mobile it can get inconsistent — occasionally missing a field, occasionally needing a manual nudge, occasionally not firing on an app that a more mature competitor would've handled without a thought. It's not broken. It's just not yet invisible, and invisible is the bar for autofill.
The other friction point is migration. Importing from another manager works, but the process can feel fiddly, and moving your entire credential library is exactly the moment where a clunky flow scares people off. Proton has smoothed this over time, but it's still the roughest part of onboarding.
Neither of these is disqualifying. They're the tells of an app that's two years old competing against apps that are fifteen. The bones are excellent. The finish is still being applied.
