How to Generate a Random Password That Fits Account Rules

Generate a fresh password that matches account length and character rules, then save it safely and enable multifactor authentication.

Check minified CSS with practical examples for calculations, selector spacing and browser testing before replacing a live stylesheet.

Convert a small image to a data URL, paste the complete HTML source, fix common copying errors, and choose when to use an image URL.

Show HTML examples as readable text. Encode a tested snippet, spot double escaping, and choose the right method for source code or plain text.

Encode query values containing spaces, ampersands and plus signs. Test a complete example, parse it back, and avoid double encoding.

Troubleshoot SHA-256 text mismatches with tested newline and Unicode examples, UTF-8 byte checks, and clear hex-versus-Base64 comparisons.

Encode and decode UTF-8 text with a tested Base64 example. Understand padding, URL-safe output, decoding errors and why encoding is not encryption.

Fix invalid JSON with examples of quote, comma and bracket errors. Follow a repair workflow and check what a successful syntax test cannot prove.
