Are the passwords and codes generated on your servers?

No — generation happens in your browser. Passwords and random values come from the browser's cryptographic random number generator (crypto.getRandomValues), hashes are computed with the built-in WebCrypto engine, and QR codes, barcodes, and CSS snippets are drawn locally, so nothing you generate is transmitted or stored. That matters most for passwords: a password that never leaves your device cannot be logged by a server on the way. One distinction is worth knowing for QR codes. A static QR code encodes your text or link directly and is free and permanent — it keeps working no matter what happens to this site. A dynamic QR code instead points to a short link we host, which is what makes it editable after printing and lets you count scans; because we have to store that destination, dynamic codes require an account and are part of Pro. Everything else on this page needs no account at all.
