Follow this guide to resolve error messages on your booking page about not being able to access your calendar.
Updated login credentials
2FA activated on your calendar account
YouCanBook.me connects to your Outlook or Google calendar using a process called Oauth authentication. It is a secure way to connect your calendar account to YouCanBook.me without sharing your password.
2FA is a second layer of security on your calendar account, that provides an additional password for you to enter before you can access your account.
Oauth standard is that whenever 2FA is enabled on an account, all existing integrations must be revoked for safety. This means that the 2FA enabled on your calendar account can break YouCanBook.me's connection with your calendar.
To resolve this, you can also re-authorize our connection each time you see this message on your booking page, however the next time you login to your calendar account with a 2FA code, it may break our connection again.
The alternative is to turn off 2FA on your calendar account that is connected to YouCanBookMe, if possible.
