While I couldn't find specific information regarding Passkeys offered by Norton, Avast, Kaspersky, or Bitdefender, I can provide you with some general insights about password managers and passkey management.
Password managers are tools designed to securely store and manage your passwords. They typically encrypt your passwords and store them in a vault protected by a master password. This allows you to have unique, complex passwords for each of your online accounts without the need to remember them all.
A passkey, on the other hand, is a type of authentication method used for encryption and decryption purposes. It is often a long string of characters or a passphrase that is used to secure your data. Passkeys are typically used in encryption algorithms to protect sensitive information.
It's worth noting that some password managers may use passkeys in their encryption process, but they may refer to it by a different name, such as a master password or encryption key. This key is used to encrypt and decrypt your stored passwords.
As you mentioned, you are already using Bitwarden for passkey management. Bitwarden is a popular open-source password manager that offers a range of features including secure password storage, autofill, and synchronization across multiple devices. It uses strong encryption algorithms to protect your data and provides the convenience of accessing your passwords from any device.
If you are specifically looking for information about passkeys offered by Norton, Avast, Kaspersky, or Bitdefender, it is recommended to visit their official websites or contact their support teams directly for accurate and up-to-date information on their password manager offerings.
