1. Choose a secure password manager. Look for one that has been tested and approved by security professionals.
2. Create unique, complex passwords for different accounts. Mixing letters, numbers, and specials characters can improve the security of your passwords.
3. Enable two-factor authentication to add an extra layer of security to your accounts.
4. Enable notifications for changes in password or login credentials.
5. Regularly audit accounts to monitor any unexpected access.
