Create a private sync key
We generate a high-entropy recovery key. It is the only way to open this profile, so keep a private copy. The browser does not store it.
Optional player profile
Keep your games when devices change
Manually sync daily progress, streaks and statistics without an email address or password. Anonymous play stays exactly as it is.

Your recovery key
This key grants access to your saved game progress. It stays only in this page's memory and is forgotten when you leave or reload. FiveLetterWords cannot recover it for you.

Delete the sync profile
This permanently removes the server copy and cannot be undone. Games already saved in this browser stay here.
Small by design
No forced registrationPlay first. Create a profile only if cross-device continuity is useful.
No personal detailsNo name, email address, password, social login or profile advertising identifier.
Safe mergeLinking keeps coherent game records from both copies. Recent cloud history is bounded; richer history stays in each browser.
Your controlThe key is never saved by the browser. Forget it immediately, or permanently delete the server copy while it is active.
