🔐 Security Considerations

Security is of utmost importance when implementing a forgot password system. We must carefully consider various security aspects to protect user accounts and prevent unauthorized access. A robust and secure password reset process is essential for maintaining user trust and data integrity.

Token Security

Token security is a critical aspect of the password reset process. Tokens are used to verify the user's identity and authorize the password reset. Therefore, it's crucial to implement robust measures to protect these tokens from being compromised.

  • [ ] Cryptographically secure token generation: Tokens should be generated using cryptographically secure methods to ensure their randomness and unpredictability. This makes it difficult for attackers to guess or generate valid tokens.
  • [ ] Token expiration enforcement: Tokens should have a limited lifespan and expire after a certain period. This reduces the window of opportunity for attackers to exploit compromised tokens.
  • [ ] Single-use token validation: Tokens should be valid for a single use only. Once a token has been used to reset the password, it should be invalidated to prevent it from being used again.
  • [ ] Secure token storage (hashed in database): Tokens should be stored securely in the database, preferably in a hashed format. This prevents attackers from directly accessing the tokens if they gain access to the database.

Rate Limiting

Rate limiting is a technique used to control the number of requests that a user can make to a system within a given timeframe. It's an essential security measure for preventing abuse and denial-of-service attacks. By limiting the rate of password reset requests, we can mitigate the risk of attackers overwhelming the system or attempting to brute-force passwords.

  • [ ] Limit password reset requests per email (5 per hour): We'll implement rate limiting to restrict the number of password reset requests that can be made from a single email address within an hour. This prevents attackers from flooding the system with password reset requests.
  • [ ] Limit OTP verification attempts (5 per token): We'll limit the number of OTP verification attempts allowed for each token. This prevents attackers from trying to guess the OTP by making multiple attempts.
  • [ ] Global rate limiting per IP address: We'll implement global rate limiting per IP address to prevent attackers from using multiple email addresses or accounts to bypass the rate limits.
  • [ ] Temporary account suspension for abuse: If a user exceeds the rate limits or exhibits suspicious activity, their account will be temporarily suspended to prevent further abuse.

Password Security

Password security is paramount to protecting user accounts. We'll enforce strong password requirements and implement measures to prevent password reuse. By ensuring that users choose strong and unique passwords, we can significantly reduce the risk of unauthorized access.

  • [ ] Enforce strong password requirements: We'll enforce strong password requirements, such as minimum length, character diversity (uppercase, lowercase, numbers, and symbols), and complexity. This encourages users to choose strong passwords that are difficult to guess.
  • [ ] Prevent password reuse: We'll prevent users from reusing their previous passwords. This forces users to create new passwords, reducing the risk of attackers using previously compromised passwords.
  • [ ] Secure password hashing (bcrypt): We'll use a strong password hashing algorithm, such as bcrypt, to securely store passwords in the database. Bcrypt is a widely used and trusted algorithm that makes it computationally expensive for attackers to crack passwords.
  • [ ] Clear password from memory after use: We'll clear passwords from memory after they are used to prevent them from being exposed in memory dumps or other security breaches.

Audit & Monitoring

Audit and monitoring are essential for detecting and responding to security incidents. By logging and monitoring password reset attempts, we can identify suspicious activity and take appropriate action to mitigate potential threats.

  • [ ] Log all password reset attempts: We'll log all password reset attempts, including the timestamp, IP address, email address, and outcome (success or failure). This provides an audit trail for security analysis and troubleshooting.
  • [ ] Monitor for suspicious patterns: We'll monitor the logs for suspicious patterns, such as multiple failed password reset attempts from the same IP address or email address. This helps us identify potential attacks or unauthorized access attempts.
  • [ ] Alert on excessive failed attempts: We'll set up alerts to notify us of excessive failed password reset attempts. This allows us to respond quickly to potential security incidents.
  • [ ] Track completion rates: We'll track the completion rates of the password reset process to identify any bottlenecks or usability issues. This helps us improve the user experience and ensure that the process is working smoothly.
