Someone told me about this webservice: https://pwpush.com/
This service is clearly for password sharing, yet the security of it is... well, not great.
Passwords and "passphrases" are sent to the server (and back) in clear (over TLS, but no E2EE), and are only ciphered on disk using a shared key for all data.
Passphrases are not even hashed by the server...
Please do not use services like that without doing an audit beforehand.
I would recommend using Bitwarden Send (https://bitwarden.com/blog/bitwarden-send-how-it-works/) or something similar if I really had to share a password to a non-tech person. To a tech person, I would send shadows generated with ssss over multiple medias.
