Weak authentication allows attackers to gain unauthorized access through password guessing, session hijacking, or bypassing login controls.
Scan for This VulnerabilityAuthentication is your first line of defense. Weak configurations like no password requirements, missing rate limiting, or insecure sessions make it easy for attackers to compromise accounts. Even with otherwise secure code, weak auth can lead to complete account takeover.
Account takeover through credential stuffing
Brute force attacks succeed without rate limiting
Session hijacking if cookies are insecure
Fake accounts if email verification is missing
Data breaches through compromised accounts
Require minimum length and complexity.
// Supabase Auth config
{
password_min_length: 8,
// Consider additional complexity rules
}Require users to confirm their email before accessing the app.
Limit login attempts to prevent brute force attacks.
// Rate limit example
const rateLimit = {
windowMs: 15 * 60 * 1000, // 15 minutes
max: 5 // 5 attempts per window
};Set appropriate flags on authentication cookies.
// Cookie settings
{
httpOnly: true, // Not accessible via JavaScript
secure: true, // HTTPS only
sameSite: 'lax' // CSRF protection
}VAS automatically scans for weak authentication and provides detailed remediation guidance.
