Signal is almost the only thing that I strongly trust.
Originally set it up to discuss patent stuff which had to be kept pretty secret, stayed for the lolz.
For small but sensitive items of data, such as bank details, I split over a couple of channels, eg SMS and email, to make it harder for any one bad actor to see all parts.
The split channel approach is clever, never thought of that. Do you find people actually follow through with the second channel or do they just reply what's the code?" in the same thread?
