It’s worth considering additional layers beyond “make it less likely to leak”. Reducing the adversarial value of information is a very good strategy. Use 2FA and change your important passwords regularly (and rotate immediately if you know of a leak). Don’t keep many secrets, if you can help it. Or understand that leaks happen and be prepared to release MORE information if needed to ensure proper framing of whatever socially-painful leak happens.
