Click Scan a QR code if a QR code is visible on the screen or manually enter the details. The QR code is usually a visual representation of the following address URL-encoded:

• Secret key (base32): the secret key (32 characters)
• Credential type: usually TOTP, but can be HOTP
• Number of digits: usually 6, but can be up to 8
• Algorithm: usually SHA-1, but can be SHA-256
