Establishing a startup involves essential security measures such as creating a branded company email account, which serves as a focal point for important communications and interactions, and employing tools like multi-factor authentication (MFA), password managers, and single sign-on (SSO) to safeguard against threats like phishing and credential stuffing. Startups are advised to prioritize securing their primary email and cloud hosting services with MFA, using options such as authenticator apps, one-time passcodes, or hardware keys, with platforms like Google and Microsoft offering various MFA solutions. Password managers are recommended for securely generating, storing, and managing passwords, mitigating the risks posed by password breaches, while SSO can streamline authentication processes by linking multiple services to a single identity, often through Google or Microsoft accounts. Kinde's approach includes using Google Workspace with enforced 2-Step Verification and hardware keys for admins, utilizing 1Password for password management, and adopting a company policy of using "Login with Google" for online services to minimize password-related challenges.
