Security Best Practices
A self-custody wallet puts you in control — which means security is in your hands too. Follow these practical steps to protect your account, your Private Key, and your device from the most common threats.
Protect your Private Key
Your Private Key is the master key to your self-custody wallet. Anyone who has it controls your assets. In a self-custody model, no one — including iCloser — can recover your wallet if the private key is lost or restore it on your behalf.
Record the phrase on paper or a metal backup and store it somewhere private. Avoid digital copies.
No legitimate iCloser screen, support agent, or website will ever ask you to type your Private Key.
Consider two separate secure locations to protect against fire, loss, or damage.
Strong passwords and two-factor authentication
Your iCloser account login protects access to the app and its features. Use a strong, unique password and enable any additional verification available to your account.
Do not reuse a password from another service. A password manager helps you keep a long, random password per account.
Two-factor authentication adds a second check at login. Where the app offers an authenticator or email verification step, turn it on and keep your backup codes safe.
Email or app verification codes are single-use and time-limited. Never read a code aloud or forward it to anyone who contacts you.
If your account offers session or device management, sign out of devices you no longer use.
Recognise and avoid phishing
Phishing tries to trick you into revealing your password, verification code, or Private Key, or into approving a transaction you did not intend. Most losses in crypto come from social engineering, not from broken technology.
| Warning sign | What to do |
|---|---|
| A message asks for your Private Key or password | Stop. No legitimate party needs it. Do not reply. |
| Urgent "your account will be locked" pressure | Slow down. Urgency is a manipulation tactic. |
| A link to a look-alike login or "support" site | Do not click. Open the app directly instead. |
| Someone offers to "help recover" your funds for a fee | This is a scam. Report and ignore. |
| An unexpected request to approve or sign a transaction | Reject it and verify what you are signing. |
Keep your device secure
Your phone is the gateway to your wallet. A secure device greatly reduces the risk of unauthorized access.
Use a strong passcode plus Face ID or Touch ID. Avoid simple or repeated patterns.
Install iOS and app updates promptly — they include security fixes.
Download iCloser from the official App Store listing. Avoid sideloaded or modified versions.
Avoid sensitive actions on untrusted networks. Watch for shoulder-surfing in public.
Common questions
Can iCloser recover my wallet if I lose my Private Key?
No. In a self-custody wallet, the Private Key is the only way to restore access. iCloser does not hold it and cannot reset a self-custody wallet for you. Store the phrase offline and keep a backup.
Will iCloser support ever ask for my password or Private Key?
Never. Anyone asking for your Private Key or password is attempting fraud. Do not share it, even with someone claiming to be support.
Is my money safer because iCloser is non-custodial?
Non-custodial means you control your keys and iCloser does not custody your funds — that removes one risk but puts backup and login security on you. Following these practices is essential.
What should I do if I think I was phished?
Stop interacting with the source, secure your device, change your password, and, if you fear your Private Key was exposed, move assets to a new wallet you control. Contact support if you need help.
