Keeping control of exchange accounts and wallets through power cuts and unstable connections
Most security advice assumes stable electricity and a working internet connection. For many readers in Ukraine, that assumption does not always hold. A power cut can drain the only phone with your authenticator, a mobile network outage can block the SMS code you need, and a recovery phrase stored on a device at home is useless if you have had to leave in a hurry. Access problems of this kind rarely lose money directly, but they can force rushed decisions, such as relying on someone else's device or skipping checks to finish a transfer before the battery dies. This guide offers a resilience plan for accounts on Binance, OKX, Bybit or Bitget and for personal wallets, built around redundancy rather than speed.
Remove single points of failure in authentication
If one phone holds every authenticator code, a dead battery is enough to lock you out. Where exchanges support it, add a passkey on a second device you control, or install the authenticator on a backup phone using the setup key when you first enable it. Do not depend on SMS as the only factor, since mobile networks may be unavailable exactly when you need them. Write down which methods are active on each exchange and keep that list with your backups, not on the phone itself.
Plan power for the devices that matter
Keep a charged power bank dedicated to your main phone and, if possible, your backup device. Make it a habit to charge both whenever power returns. Download the official exchange apps and your wallet app in advance and keep them updated while you have a connection, rather than trying to install them during an outage. If your wallet supports offline viewing of addresses, learn how it works now so that you can still receive funds without a full connection.
Store recovery material so it can travel
Recovery phrases and authenticator setup keys written on paper are vulnerable if they exist only at one address. Consider keeping a second copy in another secure place you can reach if you need to relocate, protected from water and fire. Never photograph a recovery phrase or store it in a messaging app. If you hold a hardware wallet, keep its recovery phrase separate from the device itself, and practise restoring it once so that you know the process works under pressure.
Avoid rushed transfers on borrowed devices
If an outage strikes in the middle of a planned transfer, it is usually better to wait than to finish on a borrowed phone or a public computer. Logging in on someone else's device exposes your credentials and may trigger security holds that delay you further. Do not share codes or passwords with a friend to complete a transaction for you. When the connection returns, check the withdrawal history and the destination address calmly before repeating anything, to avoid sending twice.

Scenario checkpoint
- Add a passkey or backup authenticator on a second device for each exchange account.
- Keep a charged power bank dedicated to the phone that holds your authenticator.
- Install and update exchange and wallet apps while you have a stable connection.
- Keep a second protected paper copy of recovery material in another reachable place.
- Wait for your own device instead of finishing a transfer on a borrowed phone.
