Protect registration, inspect connected sessions and understand what encryption does not prevent.

The answer in 30 seconds
End-to-end encryption protects message content in transit between participants, but a compromised phone, misleading contact or recipient screenshot remains a separate risk. Account access and linked devices deserve regular review.
Enable the available account verification protection, keep your registration code private, inspect linked devices and remove unrecognised sessions. Verify surprising requests by a separate contact route before sending money or sensitive information.
Examples to adapt
Follow the official transfer flow and check old linked sessions afterward.
Call the person through a known number before acting.
Log out of the linked session when access is no longer needed.

A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Code | Was a login code requested unexpectedly? | Keep private |
| Verification | Is extra account protection enabled? | Review |
| Devices | Do you recognise every session? | Disconnect |
| Requests | Was an urgent claim confirmed elsewhere? | Verify |
| Backup | Do you understand selected protection? | Check |
Free, no sign-up. UTF-8 text with semicolon-separated columns.
What to check
Encryption does not establish the identity or intent of the recipient.
A person in a conversation can capture or forward its content.
The security of cloud backups depends on the selected backup settings.
Common questions
Can a linked device read conversations?
A device you authorise can access account content according to the service's current design; review sessions regularly.
Is a message safe just because it is encrypted?
No. Check the sender and request, particularly for codes, payments and private files.
