Credentials
Username & Password QR Code Generator
Encode a username and password as plain text in a QR code. We strongly discourage sharing passwords via QR — use only for temporary guest WiFi-style credentials in controlled settings.
Sharing passwords in a QR code is insecure — anyone who scans can read the credentials. Never use this for bank accounts, email, or permanent passwords. Prefer the WiFi QR generator for network access, or a password manager for secure sharing.

Ideas
When this might be appropriate
Temporary guest access
One-day demo kiosk or event terminal with credentials that expire after the event.
Controlled classroom handout
Teacher distributes a shared practice account for a single lab session — rotate the password afterward.
Time-limited event WiFi portal
Some captive portals use username/password pairs — still prefer the dedicated WiFi QR when possible.
Legacy system workaround
Old equipment that cannot use modern auth — replace with safer methods as soon as feasible.
Tips
Security tips
Use temporary credentials only
Create credentials that expire or change immediately after the event — never encode your personal passwords.
Prefer the WiFi QR generator for networks
Our WiFi page encodes credentials in the standard format phones connect with automatically — safer and more convenient.
Assume the password is public
Anyone who photographs the QR can decode it. Treat encoded passwords as visible to the world.
Destroy printouts after use
Shred or delete printed codes as soon as the temporary access period ends.
