A password manager can generate and store unique credentials for exchanges, email accounts, and wallet applications. It reduces password reuse, but it does not turn a custodial account into self-custody or replace a wallet backup plan.
Use unique passwords for online accounts
Exchange and email passwords should be long, unique, and paired with strong multi-factor authentication. Recovery email and mobile-carrier security matter because attackers often target the account-reset path.
Secure email before the exchange account
An attacker who controls email may be able to reset passwords, approve devices, or hide security alerts.
Treat recovery phrases as signing authority
Anyone who learns a wallet recovery phrase may be able to recreate the wallet. Whether to store it digitally depends on the wallet’s guidance and the user’s threat model; an encrypted vault does not remove endpoint or account-compromise risk.
Separate backups reduce one-point failure
Keeping every credential and recovery secret behind one account can turn one compromise into complete loss of access.
