Using two-factor authentication (2FA)

Two-factor authentication (2FA) is a way to protect your Nextcloud account against unauthorized access. It works by requiring two different ‘proofs’ of your identity. For example, the first factor is something you know (like a password) and the second factor can be a text message you receive or a code you generate on your phone or another device.
