Crosspass is a mobile app for sending passwords and text notes. Crosspass functions peer-to-peer and encrypts end-to-end. It authenticates communicating parties by using the OPAQUE cryptographic protocol.
Crosspass facilitates the secure exchange of sensitive information—such as passwords, credit card numbers, and personal notes—directly between mobile devices. Unlike traditional methods that store data in the cloud, Crosspass ensures that your confidential information remains on your device until it's securely delivered to the intended recipient.
How It Works
1. Initiate a Share
The sender (e.g., Alice) creates a new share within the Crosspass app, generating a unique Lookup ID and a one-time PIN.
2. Out-of-Band Communication
Alice communicates the Lookup ID and PIN to the recipient (e.g., Bob) through a separate channel like email or messaging.
3. Secure Retrieval
Bob enters the Lookup ID and PIN into his Crosspass app, initiating a secure, end-to-end encrypted transfer directly from Alice's device.
4. Automatic Cleanup
Once the transfer is complete, the shared data is deleted from Alice's device. Bob's device retains the data for 24 hours before it's automatically removed.

One of the most obvious use case to use is to send crypto wallet address. It's very common thing between 2 people to exchange sensitive piece of information.
Also sending Lookup ID and PIN can be sent by two different channels: one by email and another by WhatsApp or some other IM

We also planning to integrate with LastPass and 1Password, so exchange secrets between different organizations will be much easier
I really like simplicity on how to use it. What I really like as well that there is no trace of the sensitive information since the app deletes the sensitive piece of information on receiving side. It's a simple idea, but very smart.
