Distinguish Discord login QR from a server invite QR
Discord uses QR codes for two different tasks. A login QR shown on Discord's desktop sign-in screen authorizes account access: open the Discord mobile app, use its QR scanner, review the computer and location shown, and approve only a login you started. Never scan a login QR sent by another person. A server invite QR is different; scanning it opens a discord.gg invitation that you can inspect before joining. If the invite exists as an image, use the phone gallery or QRFlow's local reader, then verify the server name and invite domain. Cancel immediately if a login prompt or destination looks unfamiliar.
Approve login QR only when you started the desktop sign-in.
Server invite QR should resolve to an expected discord.gg link.
Reject unfamiliar device, location, server, or destination details.
Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.
Discord uses QR codes for two different jobs. A login QR authorizes a desktop or browser session. A server invite QR opens a discord.gg invitation. Check which one you have before scanning.
A login QR can grant access to your account. Never scan one from a message, giveaway, moderation request, or stranger's screen. If the approval screen shows an unfamiliar computer or location, cancel it. For community owners, create an invite QR instead of sharing a login QR.
Diagnose a business card QR code that won't scan: test the file, then fix size, quiet zone, contrast, glare, blur, vCard density, styling, or print damage.
