What Should You Never Send in a Text Message?
We use text messages for almost everything: confirming dinner plans, sending grocery lists, sharing photos, and checking in on family. Because texting is so comfortable, it is easy to treat messaging like a private whispered conversation.
But unlike spoken words that vanish into the air, text messages leave permanent written records. While most everyday conversation is perfectly fine to text, certain types of information create lasting security and privacy risks when saved in chat history.
Here is a sensible, non-alarmist breakdown of what deserves extra care before you hit Send.
Not Every Secret Has the Same Level of Risk
Security shouldn't be all-or-nothing. Texting a friend the password to a guest Wi-Fi network is not the same as texting your banking credentials. We can categorize information into three practical risk levels:
Everyday Information
Guest Wi-Fi, lunch spots, general updates, package pickup codes. If seen months later, impact is negligible.
Access & Entry Codes
Garage keypad codes, streaming passwords, door PINs. Needs a little care to avoid leaving in long-term logs.
Identity & Accounts
Master passwords, bank logins, credit card CVVs, Social Security numbers, 2FA codes. Never send in plain text.
High-Risk Information to Think Twice About
Why it is sensitive: A credit card number, expiration date, and 3-digit CVV code provide everything needed for unauthorized online transactions.
What could go wrong: If either phone syncs to a family tablet, laptop, or unencrypted backup, full card details remain accessible to anyone who uses that device.
Safer alternative: Use secure payment links, Apple Pay / Google Wallet requests, or a self-destructing secret link with a short expiration timer.
Why it is sensitive: These temporary 6-digit codes are the final barrier protecting your email, social accounts, and banking profiles.
What could go wrong: Scammers frequently pose as bank representatives or tech support asking for this code. Forwarding it allows them to take over your account in real time.
Safer alternative: Never share 2FA codes with unsolicited callers. If helping a family member set up an account, do it in person or over a verified video call.
Why it is sensitive: Government identity numbers and passport scans are permanent identifiers used to open loans, file tax returns, and verify credit.
What could go wrong: Text attachments often save automatically to photo libraries and cloud photo backups, where they remain searchable forever.
Safer alternative: Upload directly through official, encrypted client portals provided by your bank, accountant, or healthcare provider.
Why it is sensitive: These codes grant direct physical entry to your living space, family, and personal belongings.
What could go wrong: Service providers, dog walkers, or cleaners change phones or leave companies. The code remains in their old text history.
Safer alternative: Program a temporary guest code on your keypad if supported, or share via an expiring link and change the code after their visit.
Why it is sensitive: Business contracts, customer lists, and financial projections may be subject to legal non-disclosure agreements (NDAs).
What could go wrong: Mixing company secrets into personal SMS threads bypasses corporate security and creates compliance risks.
Safer alternative: Share through official company channels (like Google Workspace or Microsoft OneDrive) with view-only permissions.
Quick Reference: Texting vs. Safe Alternatives
| Information Type | Risk in SMS | Recommended Method |
|---|---|---|
| Primary Account Password | High (account takeover) | Expiring Secret Link or Password Manager |
| 2FA Security Code | High (phishing risk) | In-Person / Verified Direct Entry |
| Social Security / Passport | Critical (identity theft) | Encrypted Document Portal |
| Garage / Door Keypad PIN | Medium (physical entry) | Temporary Keypad Code or Expiring Link |
| Home Guest Wi-Fi | Low (guest network) | QR Code Scan or Text Message |
