MetaMask is a self-custodial wallet, so one key piece of safety is users being educated on how to stay safe. Going to drop some links at the end of this post so you can check out some tips. It might seem like a lot, but I highly recommend checking everything out to better educate yourself on self-custody and best safety practices.
Anytime you have an amount of funds or an asset which is important to you, it is recommended to use a hardware wallet as backup. MetaMask currently supports five lines of hardware wallet: AirGap Vault, Keystone, Lattice, Ledger and Trezor. These wallets are supported on Extension, and will be able to be added to Mobile in future updates. If you purchase a hardware wallet, only buy directly from the company and not a 3rd party vendor.
The top safety and security tips I’ll share are:
Be sure your Secret Recovery Phrase is written down somewhere safe offline (piece of paper). Keep it somewhere safe. Do not screenshot it or email it to yourself.
Never share your Secret Recovery Phrase, ever. This includes never inputting it on a site, pop-up window, or form requesting it (no matter how legit it looks - scams will try to impersonate MetaMask). You never have to sync your wallet, or upgrade. We do not have access to your assets. Also remember MetaMask will never initiate contact with you through email, be careful of scams.
Confirm the links you visit and contracts you approve are legitimate. Like with anything of value, there are bad actors in the space.
Keep all software up to date (including your MetaMask),
Use antivurs software and keep it current.
Make sure your passwords are well-chosen and protected.
Don’t open suspicious attachments or click unusual links in messages, browse the web safely and avoid visiting sites that offer potentially illicit content. Many of these sites install malware on the fly or offer downloads that contain malware.
