Is Telegram Safe to Use? What They Don't Tell You (2026)
The short answer: Telegram is not end-to-end encrypted by default — and most people assume it is. That single misunderstanding is why people share things on Telegram they’d never send in an email, while Telegram’s servers can technically read every word. If you’re using Telegram for regular group chats, sharing news, or following channels, the risk is manageable if you know what you’re doing. If you’re using it because you believe your messages are private — the way Signal messages are private — you need to know something important first.
The Encryption Misconception That Matters
Telegram has a reputation as a “secure” messaging app. That reputation is largely unearned — or at minimum, it’s complicated.
Standard Telegram messages use server-side encryption called MTProto. This means your messages are encrypted in transit between your device and Telegram’s servers. But Telegram holds the decryption keys on their end. They can read your messages. Law enforcement can obtain your messages through legal process. And if Telegram’s servers were breached, your message history could be exposed.
Security experts have been direct about this: “Telegram is centralized and doesn’t use end-to-end encryption by default. I wouldn’t consider it a particularly private or secure option.”
The exception: Secret Chats. Telegram does offer a feature called Secret Chats that uses genuine end-to-end encryption. Messages in Secret Chats are not stored on Telegram’s servers, can be set to self-destruct, and cannot be forwarded. If you need genuine private communication on Telegram, Secret Chats are the only option that actually provides it. The problem is that they’re not the default, most users don’t know they exist, and they only work one-on-one — not in group chats.
Regular group chats, channels, and standard direct messages are not end-to-end encrypted. They live on Telegram’s servers and are accessible to Telegram.
What Happened to the CEO — And Why It Changed Everything
In August 2024, Pavel Durov — Telegram’s founder and CEO — was arrested at Paris Le Bourget Airport on charges relating to alleged criminal activity on the platform, including failure to cooperate with law enforcement investigations into drug trafficking and child exploitation material. He was released on $5.56 million bail and remains under judicial supervision in France.
Before the arrest, Telegram had a nearly absolute policy: it would only share user data with law enforcement in terrorism cases. Everything else was refused.
After the arrest, that policy changed dramatically. Until September 2024, Telegram had acceded to 14 US requests for user data. After the CEO’s detention, that number jumped to 900 as the company agreed to share user phone numbers and IP addresses with law enforcement in cases of fraud and other cybercrimes.
This is not necessarily a bad thing for ordinary users — cooperation with fraud investigations protects victims. But it fundamentally changes the privacy calculus for anyone who chose Telegram specifically because they believed their data would never be shared. That promise no longer holds.
The 2026 Data Leak Claim
In January 2026, a post on a leak forum announced an alleged data breach that exposed 200+ million user records, including usernames, full names, email addresses, and phone numbers. Telegram denies that users’ private data was exposed, but security researchers dispute this claim.
The breach remains disputed as of May 2026. Telegram maintains the data came from scraping public profiles rather than from any system compromise. Security researchers point out that the specific combination of data — including phone numbers linked to usernames — suggests deeper access than public scraping would allow.
Whether you consider this a confirmed breach or an unresolved dispute, the practical implication is the same: if your phone number is connected to your Telegram username, it may be in a database somewhere.
Telegram’s Real Risks in 2026
Scam and fraud activity at scale. In May 2025, crypto compliance provider Elliptic revealed that two Telegram-based marketplaces had together facilitated over $35 billion in stablecoin transactions — much of it through fraud, money laundering, and illicit commerce. Telegram channels impersonating legitimate crypto projects, investment platforms, and even government agencies are common and often look indistinguishable from the real thing.
Your phone number is your identity on Telegram. Unlike Signal, which can be used with a username, Telegram requires a phone number for registration. That number is visible to everyone in any group you join unless you specifically configure your privacy settings to hide it. In large public groups, strangers can see your phone number by default. If your number ends up in the wrong hands, SIM-swap attacks become a real risk.
Bots and phishing. Telegram’s bot infrastructure is powerful and legitimate — and also heavily abused. Fake support bots, phishing bots that steal verification codes, and bots that harvest group membership data are common. Never provide personal information or login codes to any Telegram bot, even one claiming to be official support.
How to Use Telegram More Safely
Change who can see your phone number. Settings → Privacy and Security → Phone Number → set to “Nobody” or “My Contacts.”
Use a username. Create a Telegram username so contacts can find you without needing your phone number.
Enable two-step verification. Settings → Privacy and Security → Two-Step Verification. This adds a password requirement on top of your SMS code.
Use Secret Chats for genuinely sensitive conversations. Not regular chats, not group chats — Secret Chats specifically, accessed by tapping the contact’s name and selecting “Start Secret Chat.”
Use a VPN when using Telegram. Telegram records your IP address and keeps it for up to 12 months, linking your identity to your Telegram activity. A VPN hides your IP address and encrypts your internet traffic when using the app.
Be skeptical of everything in public groups. If a Telegram channel is offering investment returns, crypto giveaways, or urgent financial opportunities — it is almost certainly fraud. These schemes follow the same playbook as Telegram crypto pump-and-dump scams.
The Bottom Line
Telegram is a powerful, feature-rich messaging platform. It is not a private messaging app in the way Signal or iMessage (with iCloud backup disabled) are private. If you use it knowing that — for channels, large groups, and general communication — the risk is manageable if you configure your privacy settings properly.
If you’re using Telegram because you believe your conversations are end-to-end encrypted and invisible to everyone except the recipient: they’re not, unless you’re specifically using Secret Chats.
