Proton Pass began syncing passkeys through browser extensions on eligible paid plans as country availability expands.
Proton Pass is pushing passkey sync into browser extensions for paid users. If you already live in Proton’s vault, that removes a daily annoyance. If you treat sync as your only backup plan, you are one bricked profile away from a bad afternoon.
What shipped
Eligible paid plans can sync passkeys through the browser extension where Proton has turned the feature on. Country availability is still widening, so a friend abroad is not proof your account qualifies today. Mobile apps continue with their own passkey paths; do not assume desktop sync fixed the phone automatically.
Install the extension from Proton’s site, sign in, and confirm a passkey appears on a second browser before you delete anything from an old store. Migrations fail quietly when people skip the dual-run week.
Recovery still matters
Passkeys shine until the device story gets weird—lost laptop, wiped profile, corporate image refresh. Keep a recovery path that is not “the same Chrome user-data folder.” Proton’s sync helps across machines you control. It does not invent a second brain for your account.
Security tooling should reduce ritual without reducing exits. Proton narrowed the ritual. You still need an exit.
Enterprise and family gotchas
Shared family plans should decide whether every adult gets passkey sync or only the household admin. Work profiles on Android can confuse where a passkey lives—test unlock on the profile you actually use for banking. If Proton’s country list still excludes you, do not half-migrate. Wait or use a different authenticator deliberately. Partial sync setups are how people lock themselves out while believing they modernized.
Break-glass drill
Once a quarter, pretend your primary laptop is gone. Recover a critical passkey on a spare device using only documented steps. Time it. If the drill fails, fix the recovery story before you enroll more sites into passkeys. Sync features make daily life smoother and make untested recovery more dangerous because confidence rises faster than preparedness. Proton improved the happy path. The drill protects the sad path.
