WJ2 Screen Lock: Protect a Logged-In Lobby on Android or iPhone

A phone that is already logged in to your wallet and the WJ2 lobby is one lost bag away from a stranger holding both. A screen lock is the cheapest fix: it asks for a PIN, pattern, password or your face or fingerprint every time the phone wakes. This page sets one up on Android and on iPhone using Android’s and Apple’s own support pages, and it belongs with the rest of the checklist in play casino on mobile safely in the browser.

Why a screen lock protects a logged-in lobby tab

Your browser keeps you signed in with cookies, so a tab you left logged in stays logged in until you log out. Anyone who can wake the phone can reach that tab. The lobby’s help centre says every operation made after logging in with your account is treated as valid, and that a fund password is entered for every withdrawal, so the lock and the two passwords work as layers.

Set a screen lock on Android, step by step

These steps come from Android’s own help page, read on 2 October 2026. Menu names can vary by phone maker.

1. Open the Settings app.
2. Tap Security. If you cannot find it, go to your phone maker’s support site.
3. Tap Screen lock. If a lock is already set, enter its PIN, pattern or password first.
4. Tap the option you want: PIN, Pattern or Password.
5. Follow the on-screen instructions.

Android’s help says a PIN takes 4 or more numbers, with 6 digits recommended and longer PINs tending to be more secure, and that a strong password is the most secure option. None and Swipe give no protection. Turning on Auto-confirm may decrease the security of the device, according to the same page.

Set a passcode on iPhone, step by step

Apple’s iPhone User Guide, read on 2 October 2026, gives these steps.

1. Open Settings.
2. Tap Face ID & Passcode, or Touch ID & Passcode on a model with a Home button.
3. Tap Turn Passcode On.
4. Tap Passcode Options to see choices. Apple calls Custom Alphanumeric Code and Custom Numeric Code the most secure.
5. Go to Settings, Display & Brightness, Auto-Lock and set a length of time.

Apple adds that setting a passcode turns on data protection with 256-bit AES encryption. It also says iPhone asks for the passcode again after a restart, after 48 hours without opening, and after five failed Face ID or Touch ID attempts. To wipe the phone after 10 wrong passcodes, scroll to the bottom of the same screen and turn on Erase Data.

Fingerprint login: add it after the lock

Fingerprint login is a convenience layer on top of a PIN, pattern or password, never a replacement for it. Android’s help says that on some devices you can sign in to the phone with your fingerprint, and points to Android’s own page for setting one up. On a phone with a fingerprint reader, set the PIN first, then add the fingerprint under the same Security screen.

Biometric login with Face ID

Biometric login on iPhone means Face ID or Touch ID, and both need the passcode first. Go to Settings, Face ID & Passcode, then Set up Face ID and follow the screen. Apple says Face ID data is encrypted, is not saved to iCloud and does not leave the iPhone, and that to turn it off for the phone you tap Reset Face ID.

1. Set the passcode first.
2. Tap Set up Face ID and follow the screen.
3. Under Use Face ID For, choose what it may do.

Autofill password: keep it behind the lock

Autofill fills your login for you, so whoever opens the phone can open what it fills. Apple lets you turn Face ID on or off for Password AutoFill under Face ID & Passcode. In Chrome on Android, tap More, Settings, Google Password Manager, Settings, then switch Offer to save passwords off if the phone is shared. Which mobile browser settings matter covers the rest of those switches.

Screen pinning: handing the phone to someone

Screen pinning keeps one screen in front until it is unpinned, which helps when a friend borrows the phone for a minute. Android’s help says to turn on App pinning first under Settings, Security. Then, on Android 9 and up, go to the screen, swipe up to the middle and hold, tap the icon at the top of the image and tap Pin. Unpinning asks for your PIN, pattern or password, so the lock has to exist before the pin means anything.

After the lock: what else a stolen phone can reach

A lock does not stop a text from reaching a thief who moves your number to another SIM. If a code arrives that you did not ask for, what an OTP meaning covers explains who must never get it, and if the lobby stops loading after you change settings, why this site can’t be reached lists the error messages and their fixes. For a lost phone, do this in order:

1. Change your wallet password from another device.
2. Change your lobby login password and fund password.
3. Ask the lobby’s 24/7 Customer Service chat to help you secure the account.
