请提供一个由数字和字母组成的密码。
f7Gh9kLm3nJp2qRt5wE is an example of a password that consists of both letters and numbers. 

To create a secure password, it is recommended to use a combination of upper and lowercase letters, numbers, and special characters, with a minimum of 8 characters. Avoid using easily guessable information such as birthdays or dictionary words, and avoid using the same password across multiple accounts. Consider using a password manager to generate and store strong, unique passwords for each account.
