About Secure Login and Protecting Your Crypto
This page is designed to show a secure, user-friendly login experience for a self-custodial crypto wallet. Unlike custodial accounts, where an external provider holds your keys, a self-custodial wallet gives you sole control of the cryptographic keys that control your funds. This added responsibility brings powerful ownership benefits — but it also introduces a greater need for careful practices around backups, device security, and transaction verification.
Best practices begin with device choice. Where possible, use a hardware security module (HSM) or dedicated hardware wallet that stores private keys in a secure environment that is not directly connected to the internet. These devices sign transactions offline and display transaction details on a screen you can trust, reducing exposure to remote attacks that might try to swap recipient addresses or modify amounts.
Next, use strong, unique passwords for any associated online accounts and enable two-factor authentication (2FA) for account-level protections such as email or identity management. However, remember that 2FA complements but does not replace private-key security: if someone obtains your seed phrase or private key, 2FA cannot recover those funds. Treat your recovery phrase as the highest-sensitivity secret; never enter it into a website, a chat, or an email. Recovery phrases belong offline in a secure backup like a hardware backup device, a safe, or a securely stored metal backup.
Phishing remains one of the most common attack vectors. Always validate that you are using the official application or verified software source before entering credentials or connecting devices. Verify URLs carefully — attackers often create near-identical domains to trick users. Where available, use bookmarks or the platform's official app store links; avoid following random links from social media or unsolicited emails. When pairing a hardware device for the first time, confirm the device’s fingerprint or attestation string via the official support guidance so you can be confident it is genuine.
Transaction verification is another critical habit. Before approving any transaction on a hardware device, read the entire transaction summary on the device's screen: confirm sender and recipient addresses, token amounts, and any smart contract interactions. Some malicious browser extensions or compromised hosts can hide or alter transaction details displayed in the host application; the device provides the last line of defense by showing what will actually be signed.
When sharing technical details for support — for example, logs, transaction hashes, or addresses — take care to redact or avoid sharing private keys or recovery phrases. Legitimate support teams will never ask for your private key or the complete recovery phrase. If someone asks for that information, treat it as a scam and stop all communication.
For developers and system architects implementing a wallet login flow, follow standard web security practices: enforce HTTPS everywhere, use secure cookies with the SameSite attribute, implement short-lived access tokens with renewal via refresh tokens stored securely, and apply rate-limiting to authentication endpoints. Provide strong device-binding and session revocation flows so users can invalidate sessions if they suspect compromise. Offer clear educational resources in the UI about backups and account recovery so users can take protective action proactively.
Finally, maintain an incident response plan that includes steps to inform users, provide recommended mitigation actions (such as moving funds to a new address), and coordinate with platform or chain-level infrastructure if needed. Education, layered defenses, and simple, clear UI prompts around verification and backup can dramatically reduce risk for end users.
