Atomic wallet security guide protect your crypto assets

Immediately generate and physically record your mnemonic phrase. This sequence of words, often called a seed or recovery phrase, is the master key to your entire portfolio. Store it offline, away from cameras and potential physical damage; a metal engraving withstands fire and water far better than paper. Never input this phrase on any website or share it, as it directly translates to your private keys.


Every access code for the application itself must be robust and unique. Utilize a lengthy, complex password managed by a dedicated password service. This layer prevents unauthorized entry even if a device is compromised. For each operation to sign a transaction or send funds, enable all available biometric and multi-factor authentication checks; these create critical friction against illicit transfers.


The core secret, your private key, should never leave the confines of the software's encrypted storage. It remains unseen during standard use. When you approve a payment, you are cryptographically signing with this key, proving ownership without exposing it. Verify receiving addresses character-by-character before confirming any operation, as a single mistake can result in irreversible loss.


Regularly update the software to incorporate the latest protective patches. Isolate your main holdings in a dedicated, air-gapped storage solution, moving only necessary amounts to a connected environment for active trading or spending. This practice limits exposure during any single event, ensuring the bulk of your resources remains inaccessible to network-based threats.

Atomic Wallet Security Guide: Protect Your Crypto Assets

Never share the twelve or twenty-four-word mnemonic with anyone; this recovery phrase is the master key to your entire portfolio, and its exposure guarantees irreversible loss.


Enable all available in-app shielding features, such as transaction encryption and a custom PIN for every access attempt, ensuring a local password protects the vault before you can sign a transaction or send funds.


Treat the private key for each individual coin with the same extreme caution as your primary seed phrase, storing them offline on encrypted hardware or physically engraved on steel plates, disconnected from any network.


Verify receiving addresses meticulously and double-check every detail before confirming any transfer.

How to Generate and Store Your 12-Word Backup Phrase

Immediately write the recovery phrase on durable material like stainless steel, never digitally.


This sequence is a direct representation of your private key; anyone who sees it can move funds and claim staking rewards. Isolate it completely from internet-connected devices, including cameras and note-taking applications.


Verify the written words twice against the screen before finalizing the setup. A single incorrect term will render the backup useless when you need to restore access.


Store multiple copies in separate, secure physical locations to mitigate risk from fire or loss. Never share this phrase to "validate" an account or sign transaction requests received via email or messages–legitimate services will never ask for it.


Use a strong, unique password to encrypt the software holding your holdings, but understand this password only protects the local application; it does not replace the absolute authority of the recovery phrase, which is the master key to all linked addresses and their contents.

FAQ:
I just installed Atomic Wallet. What are the absolute first things I should do to make sure it's secure?

Right after installing, your priority is securing the wallet's recovery phrase. Write down the 12-word seed phrase on paper, not on any digital device. Store this paper in a safe, private place, like a lockbox. Do not share these words with anyone, ever. Atomic Wallet staff will never ask for them. Next, immediately set a strong, unique password for the wallet application itself. This password encrypts the wallet data on your device. Finally, enable two-factor authentication (2FA) on your Atomic Wallet account if you use its built-in exchange services. These three steps—protecting the seed phrase, setting a local password, and using 2FA—form your core security foundation.

Is it safe to connect my Atomic Wallet to decentralized apps (dApps)?

Connecting to dApps carries risk. When you connect, you grant certain permissions to that application. Only connect to well-known, reputable dApps you actively choose to use. Never connect your wallet to a site from an unsolicited link. Before approving any transaction, carefully review the details shown in your Atomic Wallet interface. Be wary of requests for unlimited spending approvals; where possible, set a custom spending limit. After you finish using a dApp, you can disconnect it from the wallet's connection settings. Treat wallet connections like handing out a key—be selective and revoke access when done.

My computer got a virus. Are my crypto assets in Atomic Wallet now stolen?

Not necessarily, but you must act with caution. A virus can compromise files and keystrokes on your device. Since your seed phrase is the master key, its safety is paramount. If you typed or stored the seed phrase on the infected computer, consider your wallet at high risk. You should move your funds to a new, secure wallet created on a clean device. Use the "Send" function in Atomic Wallet to transfer assets to the new wallet's address. This requires knowing your password and having access, but does not require entering the seed phrase on the compromised machine. After securing funds, wipe the infected computer clean before any further crypto use.

What happens if I lose my phone or laptop where Atomic Wallet is installed?

If you lose the device, you do not lose your cryptocurrency. Your assets exist on the blockchain, not the device. The device only holds the keys to access them. To regain access, install atomic wallet not opening (extension-dapp.com) Wallet on a new, trusted device. During setup, select "Import Wallet" and enter your original 12-word recovery phrase. This will restore your entire wallet with all balances and transaction history. This is why protecting the seed phrase is critical—it is your only backup. Without it, funds are permanently inaccessible. Having the phrase means you can recover your wallet; losing the device is an inconvenience, not a catastrophe.
