A lock for the person beside you
Six digits in front of Siren, asked when it opens and after it has been out of sight — how long is yours to set, including never. The code is checked on this phone and never sent anywhere, and ten wrong tries end the session rather than lock you out.
How it works
Choose six digits. Siren asks for them when it opens, and after it has been off the screen for a while.
Choose when it asks again: straight away, after some minutes, after an hour, or only when it opens. The clock runs only while Siren is off the screen.
Use Face ID or a fingerprint if your phone offers one to Siren. The code still works when it will not read you.
Ten wrong tries sign this device out rather than locking you out. You get back in with a recovery code or another phone of yours.
Where to find it
You → Safety and privacy → Lock the app.
What it will not do
The code is never sent to Siren, so nobody, including us, can tell anyone what it is.
The condition
Face and fingerprint need a phone that offers them, and Siren says whether yours does rather than letting you assume it.
Why it works this way
The person most likely to open your phone is often in the same room. A code checked on the phone itself protects you from them without sending anything anywhere, and signing out after ten tries gives a guesser nothing while leaving you a way back in.
Free forever, for every woman here.
