Explanation

The most secure password technique is the one-time password. A one-time password is a password that is valid for only one login session or transaction, and that is randomly generated or derived from a secret key or algorithm. A one-time password can help to enhance the security of the authentication process, by preventing the password from being reused, guessed, stolen, or intercepted by unauthorized parties. A one-time password can also help to protect against various password-based attacks, such as replay, brute force, or phishing attacks. A one-time password can be implemented by using various methods or techniques, such as hardware tokens, software tokens, SMS messages, or biometric factors. Passphrase, cognitive password, or ciphertext are not the most secure password techniques, as they are either less complex, less random, or less dynamic than the one-time password.
