Telegram Privacy & Security Guide 2026
Telegram offers excellent privacy features when configured properly, but its defaults expose phone numbers and last-seen timestamps to anyone who has your number in their contacts.
Set Who can see my phone number to Nobody and let a username stand in for it — the default here exposes the one thing you most want hidden. Then set Last seen & online to Nobody and restrict Who can add me to groups to My Contacts — being pulled into a public group by a stranger is how most Telegram exposure begins.
Key steps to lock down Telegram in 2026
- Settings → Privacy and Security.
- Set Who can see my phone number to Nobody.
- Set Last seen & online to Nobody.
- Use Secret chats with self-destruct timers for sensitive conversations.
- Turn on Two-step verification with a strong password.
- Enable Passcode lock on the app itself.
- Set Who can add me to groups to My Contacts only.
- Disable Suggest contacts.
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 Telegram 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.
