Start with non-negotiable principles
Learning Device Security is less about memorizing labels and more about knowing where each piece of information appears in a real workflow. For example, when reviewing system updates, also check screen locks and browser extensions. The same-looking address or asset can behave differently across networks, and interface labels are not a substitute for verifying the network, contract or transaction details. After an action, use the transaction record and a suitable block explorer to compare the transaction hash, status and confirmation progress.
When using features related to Device Security, several on-chain details often appear at the same time, so it helps to separate what each one represents. Start by identifying the exact screen locks, then verify that browser extensions matches your intention. If public Wi-Fi is involved, do not rely on a familiar name or icon alone; use the full address, network identifier, contract details or request text. Any step that requires a signature or transaction should be reviewed again immediately before confirmation.
- When reviewing system updates, also confirm that screen locks matches the intended action and selected network.
- When reviewing screen locks, also confirm that browser extensions matches the intended action and selected network.
- When reviewing browser extensions, also confirm that public Wi-Fi matches the intended action and selected network.
Understand how common risks appear
Most decisions around Device Security happen before a confirmation, which makes a repeatable review process more useful than relying on recovery afterward. When browser extensions, public Wi-Fi and shared computers appear together, use a fixed order: identify the object, confirm the network and permissions, then consider the on-chain result. This turns a vague sense of familiarity into information that can be cross-checked, and it gives you a clear point to stop when something does not match.
From an on-chain perspective, Device Security is not a single button or screen; it connects accounts, networks, permissions and transaction states. On-chain transactions generally cannot be unilaterally reversed by a wallet after they are confirmed. An error involving public Wi-Fi may therefore have limited recovery options. Check shared computers before broadcasting and keep a clear record of system updates; prevention is more reliable than assuming an action can be undone later.

Recognize abnormal requests
A practical way to study Device Security is to break the workflow into four questions: what is the object, which parameters matter, what result will be created, and what record can be checked later. An interface description of shared computers is only the starting point. What matters is its relationship with system updates and screen locks. Different networks, contracts and DApps can use different parameters, so each request should be evaluated in its current context rather than copied from a previous habit.
For everyday wallet use, the most useful knowledge about Device Security is the ability to spot inconsistent information before approving an action. If any detail cannot be verified—such as an unknown source for system updates, an unexpected screen locks, or unclear wording around browser extensions—stop before confirming and return to a trusted source. Safe wallet use does not depend on urgency, and it never requires you to send a seed phrase, private key or verification code to another person.

- When reviewing shared computers, also confirm that system updates matches the intended action and selected network.
Keep your seed phrase and private key under your own control. Official staff will not ask for a seed phrase, private key or verification code; review every signature and approval before confirming.
