I commonly decide to use Keybase Teams because of the need for a BYOK solution to securely sharing critical data, which could be expired, and was TOFU-safe.
- BYOK ensured that we could rotate keys, and be in control of those keys rather than delegating them to a service to hold the root keys.
- Expiry was important, because we needed messages with certain risky information to disappear, to ensure against hacking (even despite our procedures).
- TOFU means 'trust on first use' and is reflected int he way that information is inaccessible to a use if they needed to do anything that interrupts the ability to trust their account — such a password reset.
These together allowed us to use this tool within our data security chain.
