What is an encryption or security key?
Your security key is an encrypted password that allows you to retrieve your account in the instance that you need to switch devices. Your chats are end-to-end encrypted, which means no one has access to your messages, not even FYI. Your security key is very important as it’s the only way to retrieve your account and messages in the event of data loss.
Where can I download my encryption or security key?
You can download your encryption key by navigating to your Profile > Settings > Security.
You will then be prompted to enter your phone's passcode. Once you do, you can save your encryption Key by following the steps for your device.
iOS
Save > Save Image
Android
Tap Save > FYI Download
Note: If you are not prompted to enter your passcode, you will have to ensure you have a passcode enabled on your device. Otherwise, you will not be able to see the QR code.
