Original GitHub issue: https://github.com/nextcloud/twofactor_gateway/issues/249

I was just having trouble setting up CalDav on MacOS 10.14.5, with my Mac constantly giving 'Unable to verify account name or password' messages when trying to set up CalDav. I'm not sure if this is only an issue with twofactor_gateway or if all Nextcloud 2FA apps exhibit this issue. I've also only tried with Telegram, but anyway:

Steps to reproduce:

Enable Telegram 2FA in security settings
Go to MacOS System Preferences > Internet Accounts > Add New CalDav Account
Setup your CalDav account using 'manual/advanced' method entering username, password and URL as per the URL in Calendar app on NextCloud.
Click 'Login' and note the error 'Unable to verify account name or password'

After disabling Telegram 2FA I can confirm setup works just fine.

Hi,

you have to use app passwords on MacOS: https://docs.nextcloud.com/server/stable/user_manual/user_2fa.html#using-client-applications-with-two-factor-authentication
