Choose the source
Team2FA accepts a setup key or otpauth URI, and supported browsers can scan with a camera, a chosen screenshot or a shared screen. Use the original setup prompt from the service where possible. Confirm the issuer and account label before saving.
What happens on the device
QR images and capture streams are decoded locally in the browser rather than uploaded as image files. Camera and screen sharing stop when scanning finishes or the dialog closes. Browser permission prompts may appear.
Google Authenticator exports
Use the import wizard to scan every QR in an export before confirming. Review the service, account and code settings for each entry, select only the entries you need, and inspect per account results when duplicates are found.
After adding
Place the entry in the appropriate group, verify that its code works with the external service, then remove unsecured screenshots or notes containing the seed. A QR code is another representation of the permanent seed.
