A scenario you hope never happens
In one second, you lose every password, every contact, every PIN, every ID number, every 2FA code. You're standing on a street corner with nothing but your memory.
What if you could get it all back
from any browser on earth?
OhNo is an encrypted emergency vault. Store your critical information once, access it anywhere — hotel lobby, library, borrowed phone. All you need is a URL and your memory.

Questions
Your data is permanently lost. We use zero-knowledge encryption — we never see your password and cannot reset it. This is a deliberate security guarantee.
OhNo is built for this exact scenario. Your data lives only in browser memory — no cookies, no local storage, no cache. Close the tab and everything is gone.
Password managers are for daily use and require an app. OhNo is a last-resort vault — no install, accessible from any browser with just a URL and your memory.
No. Everything is encrypted in your browser with AES-256 before it reaches our servers. We store only encrypted blobs. Even a full database breach yields nothing readable.
