Set up Underlock. None of the steps asks who you are.
We make Underlock, a private vault for photos, videos, files and notes. You need an iPhone with iOS 17 or later, and a pen and paper.
Coming soon to the App Store- Free for one vault
- No account
- Encrypted on your phone
Setup, screen by screen
Underlock is coming soon to the App Store. Here’s how it will work.
Open Underlock. Tap Get started. Three short cards explain how Underlock works. Tap Next on each card.
On the Draw your pattern screen, draw a pattern that connects at least 6 dots on a 5 by 5 grid. A pattern of 8 dots or more is harder to guess. Draw the same pattern again.
Get a pen and paper. Tap I’m ready. Write down the 12 words Underlock shows you, in order. These 12 words are your recovery phrase. Tap I’ve written it down.
Underlock then asks for 3 of your words, such as words 3, 7 and 11. For each one, choose the word your paper shows from a short list.
Your vault opens, empty. To add photos, videos, files or notes, tap Add.
Questions
No. Your iPhone still unlocks with your passcode, Face ID or Touch ID. Your vault opens with your own pattern, not your passcode.
Yes. At setup, tap Use a passphrase instead on the Draw your pattern screen. A passphrase is a few words, like a short sentence you’ll remember. Underlock tells you if a passphrase is too short. To open your vault, you type your passphrase. Underlock still shows you 12 words to write down, and the 12 words get you back in if you forget your passphrase.
When Underlock asks for your pattern, tap Use recovery phrase instead. Type your 12 words. Then choose a new pattern. If you lose both your pattern and your 12 words, nobody can open your vault, not even us. Get back in with your 12 words
Yes. Underlock is free forever: one vault, no file limit. If the free plan ever changes, you keep the plan you started with. More vaults come with Pro, Underlock’s paid plan.
