Observation
The one password we still type from memory.
Idea
What if onboarding asked a different question?
A short, personal sentence becomes a compliant master password.
The obstacle becomes a threshold.
Friction
Where does the idea break?
Intentions change, and a meaningful sentence may be easier to guess.
Product
What does this actually become?
A password manager built around guided renewal.
What remains.
Vow is a thought experiment.
