Seed Phrase & Private Keys

Seed phrases and private keys can recover or control wallet accounts, so they are not ordinary login credentials. Offline backup aims to reduce network exposure and accidental loss while avoiding screenshots, cloud synchronization, and sharing recovery material with anyone.

Users keep control of seed phrases and private keys. imtoken will never ask for a seed phrase, private key, or verification code. Verify the address, network, and amount before sending and inspect approval scope before authorizing.

Core security principles

Focus: seed phrases, private keys, and derived accounts

Seed phrases and private keys can recover or control wallet accounts, so they are not ordinary login credentials. Offline backup aims to reduce network exposure and accidental loss while avoiding screenshots, cloud synchronization, and sharing recovery material with anyone.

Start by separating secret material from public, verifiable information. Seed phrases, private keys, and verification codes should not be sent to other people; addresses, networks, transaction hashes, and public contract details can be used for self-service verification.

When permissions may change, place seed phrases, private keys, and derived accounts in one risk model: decide whether the information should appear at all, whether the source is trustworthy, and whether the action can change assets or permissions.

Common risk scenarios

Focus: derived accounts, offline records, and recovery testing

When deciding whether a result is final, risk can come from a page, device, network environment, or social pressure. offline records, recovery testing, and screenshot risk may look like different situations, but each can cause a user to reveal information or authorize a request without sufficient review.

Urgent time-pressure prompts, impersonated support, remote-control requests, instructions to copy recovery material, look-alike domains, and unexpected approvals all deserve caution. Knowing some public information about an account does not prove a person's identity.

Use public computers and public networks cautiously. Important wallet operations are easier to protect on a device and network you control, with operating-system, browser, and security settings you understand.

Recognize suspicious requests

Focus: recovery testing, screenshot risk, and cloud sync

When building a repeatable routine, ask four questions when a request seems unusual: who is the source, why is the permission required, what can the request change, and where can the outcome be verified? If any answer is unclear, stopping is appropriate.

When reviewing cloud sync and fake support, verify more than a name or icon. Check the domain, address, network, contract object, and permission scope because visual similarity and habitual clicking are common sources of error.

Connecting a wallet does not mean every signing request should be accepted. Message signing, transaction signing, and token approval have different effects and should be evaluated independently.

Respond in a deliberate order

Focus: cloud sync, fake support, and seed phrases

From a risk-boundary perspective, if you discover a suspicious situation, reduce new risk first: stop signing, approving, or transferring; leave the suspicious page; preserve public evidence such as transaction hashes; and reopen a trusted entry point to inspect account and network state.

If the device environment may be compromised, stop performing important actions there and review recently installed software, browser extensions, remote-control tools, and clipboard behavior. Do not attempt to 'repair' a wallet through an untrusted page.

Consider revoking permissions that are no longer needed and disconnect sessions you no longer use. The exact method can differ by chain and contract, so identify the network and object first.

Turn security checks into a routine

Focus: seed phrases, private keys, and derived accounts

In practical use, make the security sequence repeatable: do not disclose secret material, re-check the domain, verify address and network character by character, read signatures in full, inspect spender and allowance, and review permissions after use.

No wallet can credibly promise a promise that all risk is eliminated, that assets can no asset-loss incident can ever occur, or complete prevention of every scam. Security controls reduce risk and make suspicious situations easier to notice; they do not eliminate every possible threat.

imtoken will never ask for a seed phrase, private key, or verification code and cannot recover a user's private key. Users keep their own recovery material and should independently decide whether to interact with third-party DApps or smart contracts.

Operation and security checklist

  • Keep seed phrases and private keys offline and under your control
  • Official personnel will not ask for seed phrases, private keys, or verification codes
  • Verify domains, addresses, and networks carefully
  • Review every signature and approval independently
  • Inspect the spender and permission scope
  • Consider revoking approvals that are no longer needed
  • Use public devices and public networks cautiously
