Use a different password for every account and store it in a password manager. Metadata cleanup, visible redaction and content review address different information. Removing a file’s location metadata does not hide a street sign inside the image. Likewise, detecting a name in text is not a guarantee that every identifying detail has been found.\nCommon questions\nIs hiding text with a colored box enough?\nA visual cover can leave the original information in the file. A redaction workflow needs to remove the underlying content and verify the saved result.\nCan automatic suggestions guarantee anonymity?\nNo. Context, indirect identifiers and missed entities can still identify someone. Use automated suggestions as a review aid and inspect the final output.\nContinue your workflow:\nPassphrase generator\n,\nWifi QR code\n,\nUUID generator\n.",

Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nCryptographic randomness, length and character controls; no secret logging or network submission.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"password-generator\",\n  \"category\": \"privacy-tools\",\n  \"built\": true,\n  \"requirements\": \"Cryptographic randomness, length and character controls; no secret logging or network submission.\",\n  \"implementation\": {\n    \"fields\": [\n      {\n        \"key\": \"length\",\n        \"label\": \"Length\",\n        \"value\": 20,\n        \"type\": \"number\"\n      },\n      {\n        \"key\": \"upper\",\n        \"label\": \"Uppercase\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      },\n      {\n        \"key\": \"lower\",\n        \"label\": \"Lowercase\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      },\n      {\n        \"key\": \"digits\",\n        \"label\": \"Numbers\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      },\n      {\n        \"key\": \"symbols\",\n        \"label\": \"Symbols\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      }\n    ],\n    \"input\": false,\n    \"note\": \"Secure browser randomness; each selected group appears.

([Markdown](https://happytails.ai/en/privacy-tools/passphrase-generator.md))\n\n- [Wifi QR code](https://happytails.ai/en/marketing-tools/wifi-qr-code/): SSID/password/auth fields and proper escaping. ([Markdown](https://happytails.ai/en/marketing-tools/wifi-qr-code.md))\n\n- [UUID generator](https://happytails.ai/en/developer-tools/uuid-generator/): Declare UUID versions, secure randomness for v4 and batch copy/export limits. ([Markdown](https://happytails.ai/en/developer-tools/uuid-generator.md))\n\n## How to use Password generator\n\n1. Enter the values you want to calculate and choose the relevant units or settings.\n2. Review the settings, then choose Run Password generator.\n3. Review the result, then use Copy result or a download link when available.\n\n## Working with password generator\n\nPassword and passphrase generators need cryptographically secure randomness. Use a different password for every account and store it in a password manager. Metadata cleanup, visible redaction and content review address different information. Removing a file’s location metadata does not hide a street sign inside the image. Likewise, detecting a name in text is not a guarantee that every identifying detail has been found.\n\n## Common questions\n\n### Is hiding text with a colored box enough?\n\nA visual cover can leave the original information in the file. A redaction workflow needs to remove the underlying content and verify the saved result.\n\n### Can automatic suggestions guarantee anonymity?\n\nNo. Context, indirect identifiers and missed entities can still identify someone. Use automated suggestions as a review aid and inspect the final output.\n\nContinue your workflow: [Passphrase generator](https://happytails.ai/en/privacy-tools/passphrase-generator/), [Wifi QR code](https://happytails.ai/en/marketing-tools/wifi-qr-code/), [UUID generator](https://happytails.ai/en/developer-tools/uuid-generator/).\n"
