Password Generator
Generate strong random passwords with configurable length and character sets.
Output will appear here.About this Password Generator
Password Generator creates strong random passwords using the browser's cryptographic random number generator. Strong, unique passwords for every account remain the single most effective defense against credential stuffing and account takeover. The generator supports configurable length, character sets, and exclusions, and never sends generated values to a server. It is the everyday tool for engineers provisioning service accounts, security teams setting bootstrap credentials, and individuals seeding a password manager.
This page is statically generated for organic search and enhanced with client-side interactivity for privacy. The tool is useful for quick checks, documentation, QA workflows, and repeat production tasks where copying reliable output matters.

Use cases
Seed a password manager
Generate a unique password for every account and store it in 1Password, Bitwarden, or your manager of choice.
Service account credentials
Create high-entropy passwords for internal service accounts that humans rarely log into.
Bootstrap admin accounts
Generate the initial admin password during system setup so it is not predictable.
API client secrets
Generate API client secrets and rotate them on a regular schedule.
Hardware device defaults
Replace factory default passwords with random values when provisioning IoT devices and routers.

In-depth guide
What makes a password strong
Strength is measured in bits of entropy. Each random character adds entropy proportional to the size of the alphabet it was drawn from. A 12-character random password drawn from a 96-character alphabet has roughly 80 bits of entropy - far beyond brute-force range for offline attacks today. The catch is that humans cannot remember 80 bits of randomness, which is why password managers exist.
Length versus complexity
Doubling the length of a random password adds more entropy than adding one new character class. A 20-character lowercase-only password is stronger than a 10-character password with mixed case, digits, and symbols. Modern guidance (NIST SP 800-63B) emphasizes length over complexity rules and discourages forced periodic rotation.
Passphrase versus random string
If a human must type or remember the password, a passphrase (4-6 random words) trades off entropy density for memorability. The classic 'correct horse battery staple' example uses about 44 bits of entropy from a 7776-word list - strong enough for accounts protected by rate limiting and MFA. For machine-only secrets, prefer a long random string.
Where passwords still matter
Passwords protect the password manager itself, encryption keys, recovery codes, and any account that does not yet support passkeys or hardware security keys. Where passkeys are supported, prefer them - they remove the password from the attack surface entirely.
Practical generation guidance
For most accounts, generate 20+ character passwords with full character class, store them in a manager, and enable MFA. For accounts that must be typed (legacy systems, kiosks), generate a passphrase. For service-to-service secrets, use 32 or more characters and rotate at least annually. Always log password creation and rotation events for audit.
Rotation, expiration, and modern policy
Old password policies forced rotation every 60 or 90 days. Modern guidance (NIST SP 800-63B) says scheduled rotation is harmful: it pushes users toward predictable patterns. Rotate when there is a reason - a breach, a suspected leak, a leaving employee. Otherwise, keep the strong password and rely on MFA, anomaly detection, and short-lived session tokens. The password generator is most valuable when you actually rotate. Generate a fresh value, store it in the manager, update the service, and verify access. Document the rotation in a runbook so future you (or the security audit) can trace what happened and when.
Onboarding a team to a password manager
Rolling out a password manager across a team takes more than buying licenses. Start with the most-shared accounts (production credentials, vendor logins, shared services) and migrate them into the vault. Train one person at a time, paired with someone who already uses it confidently. Audit who has access to each shared item quarterly. When someone leaves, rotate every credential they could have accessed. The password generator integrates into the manager - new accounts get strong unique values automatically, and migration of legacy weak passwords is straightforward once the workflow is established.
