Question: I need a secure way to authenticate requests from coworkers or friends when sharing sensitive information, can you suggest a solution?

ShakeMyHand is a serious authentication app that uses unique three-word passphrases, paired phones that are linked by QR code scanning, and time-based passphrases that change every few minutes. It uses serious cryptography to generate custom, unbreakable codes for each pair of people. It's good for verifying digital interactions in situations like financial transactions and team data security without needing a middleman or central server.

Another good option is BoxyHQ, an information security platform that offers a variety of tools to protect sensitive data and lock down cloud software. That includes features like Enterprise SSO with SAML and OpenID Connect, Directory Sync with SCIM 2.0 protocol, and Audit Logs for logging and searching activity. It's designed to help companies improve security and compliance with industry standards, so it's a good option for startups and enterprises.
