Password Generator: Build Strong, Compliant Credentials
A password generator produces high-entropy passwords tailored to your policy—length, symbols, numbers, and exclusions. It removes guesswork and prevents weak or reused credentials.
Below we cover how it works, what makes a password strong, and how to align with compliance rules without sacrificing usability.
What Makes a Strong Password?
- Length: aim for 12–16+ characters as a baseline; longer for admin accounts
- Entropy: mix uppercase, lowercase, numbers, and symbols without predictable patterns
- Uniqueness: never reuse across sites; breach reuse is the top risk
- Resistance to guesswork: avoid dictionary words, dates, or keyboard walks
How Our Generator Helps
- Configurable length and character sets tuned to site-specific rules
- Exclude lookalike characters (O/0, l/1) to cut login typos
- Strength indicator to visualize entropy before you copy
- One-click copy plus history for quick retries without reconfiguring
- Preset templates: PCI-ready, enterprise SSO, VPN, database, or client handoffs
When to Use a Password Generator
Onboarding New Accounts
Generate vault-ready credentials for SaaS, VPNs, and admin consoles so teammates start with strong defaults.
Client Deliverables
Share temporary passwords for staging or audits with expiration plans and rotation reminders.
Developer & Ops Work
Create database users, service accounts, or API keys with symbols allowed by the target system to avoid validation errors.
Best Practices to Keep Passwords Safe
- Use a password manager; never store secrets in docs or chats
- Rotate credentials on schedule, especially for shared or service accounts
- Enable MFA wherever possible; strong passwords plus MFA reduce account takeover risk
- Check site-specific symbol rules to avoid rejected passwords and lockouts
- Do not reuse passwords across environments (dev, stage, prod)
Conclusion
A password generator removes the friction of creating strong, policy-compliant credentials. Combine it with MFA and a password manager to materially reduce the risk of account takeover.
