Bluesky Privacy & Security Guide 2026
Bluesky offers strong built-in controls for professionals but the AT Protocol's open architecture means every post is technically public-readable forever.

Key steps to lock down Bluesky in 2026
These are the exact settings to flip today. Each one removes a documented exposure vector that adversaries actively scrape and chain into doxxing, account-takeover, or stalking campaigns.
- Profile → Settings → Privacy.
- Set profile to Private (limited followers approval).
- Turn off search engine indexing.
- Set Who can reply to you to Followed users.
- Use App passwords for third-party clients instead of your main password.
- Enable two-factor authentication.
- Pick a self-hosted handle (your own domain) for better identity portability.
Quick checklist
- Profile visibility: Private or friends-only
- Search engine indexing: Off
- Location sharing: Off
- Two-factor authentication: Enabled (authenticator app, not SMS)
- Data partner sharing / personalized ads: Off
- Linked apps + sessions: Audited and revoked where unfamiliar
Why these settings still aren't enough
Even with every Bluesky setting locked down, your data still leaks through three channels these settings can't reach: historical exposures already in breach corpora, third-party scrapers that mirrored your old public data, and people-search aggregators that re-list your details every time you remove them. That's where continuous external monitoring becomes essential.
