Issues by Category
Proton Pass autofill not working consistently
The most repeated complaint: autofill works on most sites but fails often enough that users fall back to copy and paste. Firefox add-on reviewers call it inconsistent, and How-To Geek's review noted Proton Pass had more autofill issues than the other top contenders it tested.
Proton Pass extension keeps locking or logging out
Firefox reviewers describe the extension showing as locked after the PIN is entered, signing itself out and then refusing to sign back in. One user reports being signed out of both the app and extension shortly after an update; others note the extension signs out when browser site data is cleared.
Proton Pass not saving passwords - save prompt doesn't appear
The pop-up that offers to save a new login sometimes never appears, and on some sites the extension captures only the username or only the password. Users then have to create the login item by hand.
Proton Pass items missing or not syncing between devices
Proton's own troubleshooting page covers items that appear in one app but not another and tells users to force a manual sync. On Android, a blank vault screen is a known issue that is fixed by resetting filters or forcing synchronization.
Proton Pass 2FA authenticator and attachments are paid only
The free plan has no integrated 2FA authenticator, file attachments, single-item sharing, Emergency Access, Dark Web Monitoring or CLI. All of those require Pass Plus ($35.88/year) or a higher plan.
Proton Pass free plan limited to 10 aliases and 2 vaults
Free accounts get unlimited logins and devices but only 10 hide-my-email aliases, 2 vaults and vault sharing with 2 people. Users who start relying on aliases hit the cap and need Pass Plus for unlimited aliases.
Proton Pass price shown is a discounted first-term price
The pricing page shows Pass Plus at $2.99/month billed $35.88 for 12 months as a 40% discount, with Family and Unlimited also discounted against a struck-through regular price. Check what the plan renews at before paying.
Proton Pass Android autofill not working in Brave and Vanadium
Several Brave community threads report the Proton Pass popup or keyboard autofill bar never appearing on Android login forms, while Bitwarden works in the same browser. GrapheneOS users report the same in Vanadium, where some can only get it working by switching the autofill service back and forth or restarting the browser.
Proton Pass mobile autofill makes you search for the login
A Yahoo Tech reviewer found the keyboard autofill prompt opens the Proton Pass app, where you scroll or search for the right password, whereas Google's and Microsoft's managers show the matching login directly. Other users report app logins not showing in the keyboard even when the same site's login does.
Proton Pass support slow to fix reported bugs
Proton's developer replies on add-on store reviews mostly ask for a ticket or logs and warn that fixes may take time because of the volume of daily reports. A user who was locked out after an update says support could only point to a signed-in reset that needs another logged-in device.
Proton Pass doesn't work in Edge Enhanced Security or Safari Lockdown Mode
The extension and web app need WebAssembly, which Microsoft Edge's Enhanced Security Mode and Apple's Lockdown Mode disable. Security-conscious users - the people Proton targets - have to add an exception for pass.proton.me before it works.
Proton Pass requires a Proton account
You sign in with a Proton account, which ties your password vault to the same account as Proton Mail, VPN and Drive. Some users like the bundle; others dislike that losing access to the Proton account means losing the vault.
Regret Patterns
Common reasons users regret choosing Proton Pass.
Back to copy-paste on everyday sites
Users switch for the price and aliases, then find autofill misses enough logins that they copy and paste passwords again.
New logins never saved
The save prompt didn't appear when creating an account, so the new password wasn't stored and had to be reset.
Android autofill dead in the preferred browser
Brave or Vanadium users discover the autofill popup doesn't appear and have to change browsers or password managers.
Locked out after an update
The app and extension signed out after an update and recovery depended on still having another signed-in device.
Hit the free alias limit
Users who start using aliases everywhere run into the 10-alias cap on the free plan and have to upgrade.
2FA codes not included on free
Users moving from Bitwarden or Apple Passwords expect to keep TOTP codes in the vault and find the authenticator is paid-only.
When Proton Pass Breaks Down
Specific scenarios where Proton Pass fails or underperforms.
Multi-step or iframe login pages
Username and password on separate screens, or forms inside iframes, often stop the extension from detecting fields.
Android with Brave or Vanadium
The autofill popup or keyboard suggestion frequently doesn't appear, while other Android browsers work.
Hardened browser security modes
Edge Enhanced Security and Safari Lockdown Mode block WebAssembly, so the extension and web app stop working until pass.proton.me is exempted.
Clearing browser site data
Clearing site data can sign the extension out, and some users then struggle to sign back in.
Native mobile apps with custom login screens
App logins may not show in the keyboard suggestions even when the matching website login does.
Several password managers active at once
The browser's built-in manager or another extension competes for the same fields and autofill or saving fails.
