A four-digit code takes seconds to turn on, but it only helps if you know what it covers. This article explains how to set it up, what it stops, and what still needs separate protection.

Open the app's settings and turn on the access code option. The code has four digits, and once it is active the app asks for it each time it opens. Choose digits that are not obvious, such as a birth year or a repeated number, and do not share them. The code is optional, so nothing changes in the wallet until you switch it on.
Its job is narrow: it guards against someone reaching your wallet on an unlocked phone that is briefly in the wrong hands. Think of a phone handed to a friend, left on a desk or picked up by a stranger while the screen is open. Without the code, opening the app could be enough to see balances and reach the wallet. With it, the person hits a second barrier before they get anywhere.
No. Nexus Pay opens inside Telegram, and you can link a Google login as a second way in, so those accounts are the main entrance to your wallet. The access code is one layer on top of that login, not a substitute for it. If someone takes over your Telegram or Google account, a four-digit code on one phone will not help, so keep those accounts secured as well.
The code is set and removed in the same place: the app's settings. If you decide you do not want the extra step each time you open the app, you can switch it off there. Bear in mind that removing it also removes protection against a briefly borrowed phone.
The access code is one of several separate safeguards, and each covers a different risk.
The table below sets these layers side by side.
| Layer | What it guards against | Who controls it |
|---|---|---|
| Access code | Someone using your unlocked phone for a moment | You, in the app's settings |
| Telegram or Google login | Unauthorised sign-in to the account that opens the wallet | You, through your own account security |
| Card freeze | Unwanted card spending while you sort out a problem | You, in the app with one tap |
| Offline storage of funds | Exposure of the main share of funds to a constant network connection | The service, not a setting you change |
| Address check before sending | Sending crypto to the wrong address, which cannot be reversed | You, before every transfer |
It is optional, so the choice is yours, but the cost is one extra step when opening the app. The wallet can hold USDT, USDC, BTC and ETH and is linked to a Visa card, so an open app on a lost or borrowed phone is a real exposure whatever the balance. Many people find a few seconds of friction a fair price for closing that gap. If you rarely leave your phone unlocked or out of sight, you may value it less.
