Text Message Signing
Visit the tab “Tools”. You can type in a short text message (single line is best) and select a derivation path to be used for signing. Segwit or classic bitcoin address is an option as well.
Base64 signature in standard form is provided. The address is underneath.
Keep in mind when you share a signature, you are also sharing the public key for that address. This is a little more information than just a payment address.
