Why
A password should not live for years in a conversation.
The issue is not only sending the secret. It is what happens to it afterwards.
Shared document
A forgotten permission can leave information available much longer than intended.
PswSecure
The secret is encrypted, time-limited and automatically destroyed according to your rules.
Simple
Three steps. Nothing more.
Enter the secret
Password, API key, temporary code or confidential text.
Choose its lifetime
Set an expiration and a maximum number of views.
Send the link
The decryption key remains in the fragment of the shared link.
Designed for security
The server stores what is needed to deliver the secret, not the key that can read it.
AES-GCM encryption takes place in the browser through Web Crypto. The server receives the ciphertext and IV, while the AES key is appended after the # in the URL.

HTTP protection
