How it works
A document, photo or signature file may expose more than a question requires. An open chat expands who can receive it.
What to check and do
- Do not publish documents, addresses or secrets in open messages.
- Confirm the recipient and the channel specified by the organisation before sending.
- Do not send a signature file or its password to an unknown contact.
Learning scenario
Learning example: a group chat asks for an ID photo “to check your name”.
Self-check
Your answer stays on this page until it is closed or reloaded. No real passwords, codes or documents are needed. The result is not a security certificate.
Important limits
The Academy does not accept identification documents. Ask the provider about its service process.
