Things
Blur and passcodes
A thing can be blurred or put behind its own passcode, a list can be locked, and the whole app can be locked. All of it is free.
Why you'd care
The realistic threat is not a hacker, it is someone glancing at your screen on a train or picking up your unlocked phone. These four controls are aimed at exactly that.
The four levels
| Control | Scope | Use it for |
|---|---|---|
| Blur | One thing | A line you do not want visible while scrolling in public |
| Thing passcode | One blurred thing | A line that should need a code, not just a tap |
| List passcode | One list | A list nobody else should open |
| App passcode | Everything | Locking Twos itself when the phone is unlocked |
Blurring a thing
Open the thing's info, then turn on Blur. The thing renders obscured until you tap it, and it re-blurs when you come back to the list. It stays searchable and it is not encrypted, so treat it as a screen-privacy feature rather than a security one.
Putting a passcode on a thing
Once blur is on, a Passcode row appears under it in the same info panel. Set a 4 to 6 digit code and revealing that thing asks for the code instead of taking a plain tap. Only the owner can set or remove it, and removing it needs the current code.
This is the same idea as blur, one step stricter. The text still travels with the rest of the list, so it protects the screen, not the data.
Locking a list
A list passcode is asked for when the list is opened. See locking a list.
Locking the app
Settings Account App passcode requires a code to open Twos at all, independent of your device lock. Worth turning on if your phone is often unlocked around other people.
Going further
These are not encryption. They control what is shown on screen. For account-level security, see passwords, 2FA and the app passcode.
Blur survives sharing carefully. Think before publishing a list containing blurred things, since publishing exposes content by definition.
Settings that change this
- Settings Account App passcode locks the whole app.
Tips
- Blur is the right tool for one line. A whole locked list is the right tool for a topic.
- Add the passcode only when a tap is too easy. Blur alone already handles the person sitting next to you.
- If you share your screen for work, app passcode plus a locked list is a better setup than blurring dozens of lines.
