Get the idea right.
Unique passwords, app-based two-factor authentication, offline backups, hardware wallets, and test transactions solve different problems.
Safety & Wallets field guide
Crypto Security.
Protect the keys, protect the money
Start with a reputable wallet, a unique password, two-factor authentication, offline backups of your recovery phrase, and slow verification of every link and address. For meaningful amounts, consider a hardware wallet and a test transaction.
What it isWhy it mattersWhat can go wrongWhat to do next
Why this matters
Make yourself a hard target.
Crypto security is less about one perfect tool and more about layers that prevent one mistake from becoming a total loss.
Watch this
See the risk early.
Most losses begin with phishing, reused credentials, exposed recovery phrases, blind approvals, or rushed transfers.
Do this next
Turn knowledge into a habit.
Secure your email first, then your exchange accounts, then your wallets—starting with the assets that matter most.
Go beyond the summary
The subject in plain English.
Good crypto security is a system of small barriers. The goal is to prevent one stolen password, one malicious website, or one rushed decision from becoming a total loss.
Secure the email first
Email controls password resets and account alerts. A unique password, strong multifactor authentication, and reviewed recovery methods protect everything built on top of it.
Separate money by purpose
Keep long-term holdings, trading funds, and experimental applications in different accounts or wallets. Separation limits the blast radius.
Verify through a second path
Do not trust a link because it arrived in a message. Find the official site independently, compare addresses carefully, and confirm high-value requests through another channel.
Plan recovery before failure
Document how you or a trusted person can recover accounts, devices, and backups without putting the secrets themselves in an exposed instruction file.
Where the defenses belong
Where this matters.
- Protect email and exchange accounts
- Secure self-custody wallets
- Limit decentralized-app permissions
- Prepare for device loss or emergencies
Before you act
Verify before you sign.
- Use unique passwords and app- or hardware-based multifactor authentication.
- Install updates from official operating-system and wallet channels.
- Bookmark critical financial sites instead of following ads or DMs.
- Review token approvals and remove ones you no longer need.
- Test backups and emergency instructions before relying on them.
Common questions
Clear answers before money moves.
Is SMS two-factor authentication enough? +
It is better than no second factor, but app-based or hardware security keys generally resist phone-number takeover more effectively.
What is a wallet drainer? +
A malicious site or contract that tricks a user into signing permissions or transactions that let assets be removed.
Does antivirus make crypto safe? +
It is one layer. It cannot protect against voluntarily sharing a recovery phrase or approving a malicious transaction.
What should I do after a suspicious signature? +
Stop interacting, revoke risky approvals where appropriate, and move valuable assets to a clean wallet if key compromise is possible.
