Hi, Because of a new company policy need to switch our site email configurations from SMTP to oAuth. However, I can’t find that option in the admin panel. Any help? Thanks

SMTP sends emails (daily digests, password reset), while OAuth authenticates (and logs in) users. I don’t think they are substitutes for each other, unless I’m understanding wrong…

We switched to https://auth-email.com – it connects to the OAuth email service for you, so you can just use normal SMTP.
