Wallets, private keys and custody
Understand who controls a crypto account and what a recovery phrase actually protects.

A wallet is an access tool
A wallet shows account information and helps sign transactions. The assets are represented by records on a network; they are not small files stored inside the wallet application. An address can be shared to receive funds, while private signing material must remain secret.
Self-custody means you control the signing authority. With a custodial service, the provider controls it and records your entitlement in its own systems. A password reset at a custodian and recovery of a self-custody wallet are therefore different processes.
Recovery and devices
Many wallets derive accounts from a recovery phrase. Anyone obtaining that phrase may be able to control the accounts it restores. A hardware wallet isolates signing keys, but it cannot make a malicious transaction safe simply because you approve it on a separate device.
Read the device’s transaction details. Confirm the destination and permissions rather than trusting only a website’s description. Smart-contract wallets may support other recovery arrangements; understand the specific wallet rather than assuming all products use identical rules.
A practical learning exercise
Draw three boxes labelled application, account and network. Explain which part disappears if a phone breaks, and which information is required to recover access. Do this conceptually before placing value in a wallet.
Never send a recovery phrase to support staff, a chatbot or an alleged verification form. Keep backups protected from both unauthorized access and accidental destruction. A backup that an attacker can read is not a secure backup.
