Innago - Rental Payment Security?

[Tim Small]

I am converting my properties from collecting paper checks to ACH transfers via PM Software - Innago. The only problem is, my tenants are old and are afraid of "giving a third party their banking info"

Innago ensured me they use industry standard TLS 1.2 with 2048-bit encryption (bank level security and industry standard)

Just curious if anyone else has dealt with other tenants that are weary, if they have a good reason to be, and how I should handle the situation.

THANKS!
