DigitalOcean provides several ways to improve the security of your account, starting with enabling multi-factor authentication, which prevents unauthorized access even if the password is compromised. Additionally, using TOTP codes as a secondary factor is recommended for added security. You should also take advantage of OAuth-based login partnerships with Google and GitHub to delegate authentication. Furthermore, regularly check your security history for suspicious activity, review team membership, and regenerate API tokens and Spaces access key secrets as needed to enhance account security.
