Open →Strong randomness vs creative randomness
Password and UUID generators need cryptographically-secure randomness — we use crypto.getRandomValues(), the same source modern operating systems use for key material. Domain name and business name generators take a different approach: they combine words from curated lists with brand-friendly patterns. Both are 'random' in different senses — one for security, one for inspiration.
What makes a strong password in 2025
NIST's current guidance (SP 800-63B) is simpler than older rules: 12+ characters, any mix of types, no forced rotation, screen against known-breached lists. Length matters most — a 16-character random password has 102 bits of entropy, beyond the reach of any current computer to brute-force. Our Password Generator defaults to 64-bit minimum (16 alphanumeric + symbols). Pair with a password manager — no human should memorize more than 1-2 passwords.
UTM links done right
Most UTM links are built ad-hoc, leading to fragmented analytics: 'newsletter', 'Newsletter', 'NEWSLETTER', 'news_letter' all show as different campaigns in Google Analytics. The UTM Builder on this page enforces lowercase + hyphens and reminds you of the five-parameter taxonomy (source, medium, campaign, term, content). Standardize once, save yourself months of cleanup later.
