A question on implementing TOTP 2FA in an application. Is it ok to ask users to backup TOTP secret in a secure place during 2fa configuration process? Or it's better to provide one-time recovery codes? The argument against TOTP secret backup can be an assumption that if the secret leak it can be maliciously used without victim user ever noticing it. -- Anton Dedov Content of type "text/html" skipped
