Use this high-entropy, 20-character password if the service does not support Passkeys yet.
Generated locally in browser
For services without passkeys, generate a server-side cryptographically secure password per label—ideal for migration docs or IT handoffs. The free tool above still generates one anonymous password in your browser.
Paid plans unlock labeled bulk export (up to 50 services per file, length 16–32).

It checks whether your browser supports WebAuthn/FIDO2 and a platform authenticator (biometrics or PIN), lets you look up whether curated popular services support passkeys (such as Google or Microsoft), and generates a high-entropy fallback password in your browser for services that do not. It does not create or register passkeys for website accounts—that happens on each service’s own security settings.
A passkey is a passwordless sign-in credential based on WebAuthn/FIDO2. Your device stores a private key (often unlocked with biometrics or a PIN); the website stores only a public key. Sign-in is a challenge–response signature, not a shared password typed into a form.
When you open the tool, it reports whether WebAuthn is available, whether a user-verifying platform authenticator is available, and whether conditional mediation (passkey autofill UI) is available. If WebAuthn and a platform authenticator are both available, the tool shows that your device is ready for passkeys; otherwise it highlights the fallback password path or a hardware security key.
Create the passkey on that website’s account or security settings after you confirm the site supports passkeys. Use this tool’s service lookup for curated examples (such as Google, Apple, GitHub, or Microsoft) and follow each provider’s setup link when shown. This ToolGrid page does not register a passkey with third-party sites.
The free fallback password is 20 characters from letters, numbers, and symbols, generated locally with the Web Crypto API (crypto.getRandomValues) and not sent to a server for that single-password flow. Copy or regenerate as needed, and store it in a password manager. Paid labeled packs use a separate server-side cryptographically secure generator for bulk labeled exports.
Yes. Use Check Service Compatibility to search the curated list by name or domain (examples include Google, Amazon, Apple ID, GitHub, Microsoft, PayPal, Adobe, Netflix, Spotify, and Facebook). Results show whether that entry currently supports passkeys and may include a link to the provider’s security settings. The list is not exhaustive—always confirm on the service itself.
No. It performs browser feature detection, curated service lookup, optional AI security advice based on your device/service selection, and fallback password generation. Passkey registration uses WebAuthn on each relying party’s own site; this page does not call navigator.credentials.create() for third-party accounts.
On paid plans (or desktop builds that unlock it), you can enter service labels and generate a cryptographically secure password per label for migration docs or IT handoffs. Limits are up to 50 labels per file and password length 16–32. The free anonymous fallback above still generates one 20-character password entirely in your browser.
It sends your device compatibility flags (WebAuthn, platform authenticator, conditional mediation) and, if selected, the service name and whether that curated entry supports passkeys, then returns a short security strategy. It does not receive your fallback password or create a passkey.
Conditional mediation is the WebAuthn capability behind passkey autofill in some login fields (suggesting a passkey without a separate “Sign in with passkey” click). The environment check reports whether isConditionalMediationAvailable() is true in your current browser. Support can differ by browser version and OS even when basic WebAuthn works.

This free online passkey generator is a browser tool for passkey readiness, not for creating third-party account passkeys. It checks whether your current browser supports WebAuthn/FIDO2-style passkeys, lets you look up passkey support for a curated set of popular services (including Google, Microsoft, Apple, and others in the list), and generates a high-entropy fallback password when a service still needs one.
Passkeys themselves are registered on each website or app that offers them (for example in that provider’s security settings). This page helps you answer “does my device support passkeys?”, “does this popular service support them?”, and “what strong password can I use until it does?”
A passkey is a passwordless credential based on the WebAuthn and FIDO2 standards. Your authenticator (device biometrics, PIN, or a hardware security key) holds a private key; the website stores only a public key. Sign-in is a challenge–response signature bound to that site’s origin, so there is no shared password to phish or reuse.
Passkeys reduce phishing risk compared with typed passwords because the browser ties the credential to the correct relying party. Support still varies by browser, OS, and service—so a local compatibility check and a service lookup remain useful before you change how you sign in.
PublicKeyCredential (WebAuthn) is available, whether a user-verifying platform authenticator is available, and whether conditional mediation (passkey autofill) is available in this browser.crypto.getRandomValues). Copy or regenerate locally; this single-password flow is not sent to a server.The table below is a high-level comparison of traditional passwords and passkeys. It describes the general model; individual sites may still require passwords, recovery codes, or extra factors.
| Factor | Traditional password | Passkey (WebAuthn/FIDO2) |
|---|---|---|
| Secret storage | Server and client both know the password (or its hash). | Server stores a public key; the private key stays on the authenticator. |
| Phishing risk | Users can be tricked into typing passwords on fake sites. | Lower for phishing of the credential itself; credentials are origin-bound. |
| Guessing / stuffing | Depends on length, uniqueness, and rate limiting. | Based on asymmetric cryptography, not a reusable typed secret. |
| User experience | Remember or store many secrets. | Often biometrics, device unlock, or a hardware key—no password to memorize. |
The device check uses browser WebAuthn feature-detection APIs only: presence of window.PublicKeyCredential, isUserVerifyingPlatformAuthenticatorAvailable(), and isConditionalMediationAvailable() when present.
It does not create a credential and does not send authenticator data to ToolGrid for that check.
The free fallback password selects 20 characters from a mixed letter/number/symbol pool using crypto.getRandomValues in the browser.
Paid labeled packs use the tool’s authenticated pack API with length limits of 16–32 and up to 50 labels per file.
Summary: Free passkey generator: check WebAuthn/FIDO2 device support, see if popular sites support passkeys, and generate a secure browser fallback password.
