Gmail is a service used by many people and businesses; This service is often used to send sensitive data to other users, and while it does not have advanced encryption features, Gmail allows you to take advantage of a mode that allows you to send messages and attachments in a confidential manner, which is a useful option for protecting sensitive data from unauthorized access with it.
You can use confidential mode to set an expiration date for messages or revoke access at any time. The forwarding, copying, printing and downloading options will be disabled for the recipient of the secret message.
What you need to send confidential emails with Gmail
All you need is a Gmail account and web or app version for Android or iOS and proceed as follows:
1) Open Gmail and sign in if necessary
2) Type the email (by clicking or tapping “Write”)
3) In the window that opens, choose the code with the lock and the clock to select the secret mode: from the respective window you can specify the expiration (“Expires in one day”, “Expires in one week”, “Expires in one month”, “Expires in one day”, “Expires in one week”, “Expires in one month”, “Expires It expires in 3 months “,” Expires in 5 years “) and choose whether you want to activate the passcode request or not (the code is returned via SMS). If you are using an iPhone and iPad, this option is activated by tapping on “More…” > Secret Mode
4) If we ask for a passcode, it is necessary to indicate a phone number to allow recipients to verify their identity using the passcode received via SMS
5) The user who will receive the message can view it by pressing “View” and confirm his identity by indicating the correct passcode sent to the phone number indicated in the previous point. The expiration date will appear in the message. You can view the message and attachments until the expiration date or until the sender revokes access.
Keep in mind that even if confidential mode is to prevent recipients from accidentally sharing our email, it does not prevent them from taking screenshots or pictures of messages or their attachments.
