Using the Yubico Key on your phone is usually very simple. Depending on the model, you can connect it through **USB-C, Lightning, or NFC (tap-to-use)**. When logging into a supported app or website, it will ask for your security key—then you either plug it in or tap it to the back of your phone and confirm. It does **not automatically unlock everything**; it only works when a login requests verification. You typically **do not need a password manager app** just to use the key. The key is mainly for two-factor authentication and secure login verification. However, some users choose to use the **Yubico Authenticator app** or a separate password manager if they want to store/manage login codes or passwords. So in short: no constant connection is needed—just use the key when a supported service asks for it.

When logging into an account with a YubiKey registered, the user must have the account login credentials (username+password), and the YubiKey registered to the account. That said, you can use the YubiKey via direct plug in or NFC (if applicable). If you'd like additional clarification, please don't hesitate to reach out to our Support team! support.yubico.com/hc/en-us/requests/new
