As someone with a background in computer security: Your instincts regarding the insecurity of sending private information via email are good.Never send anything via email that you wouldn't feel comfortable mailing on a postcard unless you use a specialized encryption tool that encrypts data while in transit (you'd know if you were, because they're typically hard to set up and a pain to use).

Hide the SSID (not terribly secure, but will keep non-savvy off the network) and use WPA, not WEP, encryption with a complicated, but easy to remember password.

This protocol provides security for your information by encrypting it as it travels from your computer to our computer.

We encrypt all passwords and don't have any way of recovering them other than to re-generate a new one if someone loses it.

Record integrity is managed with hashing, encryption and secure retention and storage to ensure the document has not been altered.DocuSign and HelloSign are a couple legally authorized eSignature options.

IF you do decide to send them your results of the background check, like previously said get it in writing and if you send it electronically, ensure you encrypt it to lower the chances of identity theft. 

@Brad E.Just make sure that whoever you work with is using bank level encryption and has a perhaps has a cyber-insurance policy in place.

I respect that real estate professionals and bankers will be the last on the planet to believe that a fax machine provides more security than the worlds best encryption (even though routinely there documents are sent to wrong numbers by human error) but why in 2020 are we pushing people off a mobile app onto a web viewer to read stuff?

I've also  received texts 'from'  the USPS or UPS saying they are holding a package from March or April.Be careful out there everyone👍 I used to push back on the encrypted stuff from my bank and from escrow.. but not anymore I conform when needed..

Yes, I'm sure it's encrypted, but most people's online passwords are either easy to guess or can be hacked as well.
