Here are some proactive steps you can take to protect your accounts from password brute force attacks:

1. Reduce the number of wrong attempts users can make-locking their accounts after a designated number of unsuccessful attempts.
2. Create longer and more complex passwords using uppercase and lowercase characters, symbols, and numbers.
3. Change your passwords regularly.
4. Vet and monitor 3rd party access to your accounts and data.
5. Implement an MDM (Mobile Device Management) solution to secure iPhones and Androids.
6. Enable two-factor authentication when available.
