This page focuses on system updates, screen locks, clipboard safety, public networks and public computers. It uses operational checks and verifiable information and never asks for seed phrases, private keys, recovery words or verification codes.
Protect control first
Seed phrases and private keys are the core of wallet control. Never send them, or verification codes, to another person or enter them into unfamiliar sites, chat windows, forms or remote-support tools. imtoken staff will never request them. For this page, the specific focus is system updates, screen locks, clipboard safety, public networks and public computers. The goal is to turn the concept into a decision process: identify the network, address, contract or permission involved, then compare the request with independently verifiable information before continuing.
Recognize manipulation
Common risks include look-alike domains, fake support, fraudulent airdrops, malicious ads, clipboard replacement and remote-control requests. Scams often create urgency to push users into connecting, signing or transferring immediately. Verify through an independent source. If something involving system updates, screen locks, clipboard safety, public networks and public computers looks inconsistent, do not rely on a single screenshot or interface. Re-check the network name, public address, asset contract, transaction hash or approval target as appropriate. A prompt you do not understand is a valid reason to stop rather than confirm under pressure.
Review before you commit
Before sending assets, verify address, network and amount and consider a small test when appropriate. Before signing, inspect the source and likely asset impact. Before approving a token, review the target and permission scope. On-chain transactions generally cannot be reversed by the wallet. When system updates, screen locks, clipboard safety, public networks and public computers involves a high-value or irreversible action, consider validating the route with a smaller or lower-risk step first and retain relevant public records. A flow that requires recovery secrets before it can continue is not consistent with normal wallet-security practice.
Device hygiene matters too
Keep systems and browsers updated, use a reliable screen lock and be careful with extensions and remote-control software. Public computers and public Wi-Fi add risk. Re-check copied addresses to reduce clipboard-replacement risk. No security control can promise perfect safety. Over time, include system updates, screen locks, clipboard safety, public networks and public computers in routine reviews of device conditions, connected sites, permissions and network information. Security is not a promise that nothing can go wrong; it is a process that gives important decisions a verifiable basis and leaves room to stop when something is unclear.
Practical checklist
- Confirm that the active account and network match the intended action.
- Review the full address, network, asset and amount before transferring.
- Never send a seed phrase, private key or verification code to anyone.
- Before signing or approving a DApp request, review the domain, target and permission scope.
- Keep the transaction hash and independently verify status with the relevant block explorer.
