Device Security

Good decisions around Device Security depend on context more than on memorizing a screen. Operating system and browser updates can fix known vulnerabilities. Device locks reduce casual physical access. Untrusted apps and extensions may read sensitive information. This page therefore follows a prepare, review, act, and verify sequence, with clear stop conditions whenever the network, target, amount, permission, or expected result does not match the user’s intent.

operating system and browser updates can fix known vulnerabilities

For Device Security, seed phrases and private keys remain under the user’s control, and imtoken personnel will not ask for a seed phrase, private key, or verification code. Before transferring, signing, or approving, review the address, network, contract target, amount, and permission scope. On-chain transactions generally cannot be reversed by a wallet alone, and third-party DApps or smart contracts can introduce additional risk. Stop and verify with public information whenever the request does not match the expected action.

Core principle: Operating system and browser updates can fix known vulnerabilities

Focus on device locks reduce casual physical access

First, in Device Security, Core principle: Operating system and browser updates can fix known vulnerabilities works best as a repeatable security rule, not as a one-time setting. Operating system and browser updates can fix known vulnerabilities. Device locks reduce casual physical access. In a Device Security scenario, the practical response is to record the state before and after the action. A familiar interface, a rushed message, a supposed support agent, or an urgent promotion should never lower the standard for checking the domain, network, target, and permission being requested. If any of those details cannot be explained, stopping is safer than trying to discover the answer by signing first.

First follow-up in Device Security: Focus on device locks reduce casual physical access can be turned into a concrete review sequence. Check the domain, address, network, contract target, and permission scope before acting, then compare the expected result with the state that is actually recorded afterward. Untrusted apps and extensions may read sensitive information. Clipboard malware can replace copied recipient addresses. It is also important to manage long-lived permissions separately from one-time transactions. Troubleshooting can rely on public addresses, networks, transaction hashes, and contract records; a seed phrase, private key, or verification code is not troubleshooting data and should never be sent through chat, remote-control software, or an unfamiliar form.

Confirm operating system and browser updates can fix known vulnerabilities.
Check how device locks reduce casual physical access affects the current request.
Use untrusted apps and extensions may read sensitive information as a separate verification point.

Second, in Device Security, Common risk scenarios: Untrusted apps and extensions may read sensitive information works best as a repeatable security rule, not as a one-time setting. Untrusted apps and extensions may read sensitive information. Clipboard malware can replace copied recipient addresses. In a Device Security scenario, the practical response is to treat network context as a prerequisite for every step. A familiar interface, a rushed message, a supposed support agent, or an urgent promotion should never lower the standard for checking the domain, network, target, and permission being requested. If any of those details cannot be explained, stopping is safer than trying to discover the answer by signing first.

Second follow-up in Device Security: Focus on clipboard malware can replace copied recipient addresses can be turned into a concrete review sequence. Check the domain, address, network, contract target, and permission scope before acting, then compare the expected result with the state that is actually recorded afterward. Public Wi-Fi can increase network and phishing risk. Public computers should not retain wallet sessions or recovery material. It is also important to be especially careful with assumptions that arise from similar-looking networks. Troubleshooting can rely on public addresses, networks, transaction hashes, and contract records; a seed phrase, private key, or verification code is not troubleshooting data and should never be sent through chat, remote-control software, or an unfamiliar form.

How to recognize the issue: Public Wi-Fi can increase network and phishing risk

Focus on public computers should not retain wallet sessions or recovery material

Third, in Device Security, How to recognize the issue: Public Wi-Fi can increase network and phishing risk works best as a repeatable security rule, not as a one-time setting. Public Wi-Fi can increase network and phishing risk. Public computers should not retain wallet sessions or recovery material. In a Device Security scenario, the practical response is to avoid repeated submissions when the current state is unclear. A familiar interface, a rushed message, a supposed support agent, or an urgent promotion should never lower the standard for checking the domain, network, target, and permission being requested. If any of those details cannot be explained, stopping is safer than trying to discover the answer by signing first.

Third follow-up in Device Security: Focus on public computers should not retain wallet sessions or recovery material can be turned into a concrete review sequence. Check the domain, address, network, contract target, and permission scope before acting, then compare the expected result with the state that is actually recorded afterward. Remote-control tools expand what a third party can see and operate. Screen recording and screenshots can accidentally retain sensitive content. It is also important to distinguish a waiting state from a failed state. Troubleshooting can rely on public addresses, networks, transaction hashes, and contract records; a seed phrase, private key, or verification code is not troubleshooting data and should never be sent through chat, remote-control software, or an unfamiliar form.

Remote-control tools expand what a third party can see and operate. Screen recording and screenshots can accidentally retain sensitive content. In a Device Security scenario, the practical response is to keep secret recovery material separate from troubleshooting data. A familiar interface, a rushed message, a supposed support agent, or an urgent promotion should never lower the standard for checking the domain, network, target, and permission being requested. If any of those details cannot be explained, stopping is safer than trying to discover the answer by signing first.

Fourth follow-up in Device Security: Focus on screen recording and screenshots can accidentally retain sensitive content can be turned into a concrete review sequence. Check the domain, address, network, contract target, and permission scope before acting, then compare the expected result with the state that is actually recorded afterward. Verify application source and signing information before installation. After sensitive activity, review the device for unfamiliar software or extensions. It is also important to perform an independent review after submission. Troubleshooting can rely on public addresses, networks, transaction hashes, and contract records; a seed phrase, private key, or verification code is not troubleshooting data and should never be sent through chat, remote-control software, or an unfamiliar form.
