The process to verify a Signal contact involves sharing your per-conversation "Safety Number" with the other party via a different channel (like a phone conversation or a tweet).
To verify that you are indeed communicating with Gene Wood using Signal Private Messenger, you can verify my identity with the following steps.
- Open a Signal conversation with me and send me a message
- Click the vertical ellipsis "⋮" icon in the upper right
- Select "Chat settings"
- Select "View safety number"
- Look at the 12 sets of 5 digits. You'll see my number either as the first 6 sets or the second 6 sets.
