Gmail and "less secure apps"/KMail

Hey

I assume I'm not the only one here with a Gmail account set up in KMail/
Kontact. I wonder what you all have done with this problem of Google blocking 
"less secure apps" on Monday May 30 2022?

I'm currently using POP3 access with "plain" authentication and SSL/TLS. But I 
expect to be blocked from reading/sending e-mail with KMail in a couple of 
days.

From what I can find online I only seem to have two options.

1) Switch to IMAP and use OAuth login. 

I'm a bit nervous about this as don't have any experience with OAuth, and I 
have about 70k e-mails in my Gmail account, and I'm not sure how well Akonadi 
handles syncing that amount of e-mails these days - especially with all the 
funky IMAP folders that Gmail has.

2) Continue to use POP3 with an "app specific password" and two-factor 
authentification. 

This sounds like a total nightmare - even if I only have KMail configured to 
check new mail every 30 minutes :-)

Anybody got any advice as to a good way to go? 

I'm contemplating taking this opportunity to find a different mail provider 
also. And at the very least I probably won't make any big decisions or moves 
until I've installed 15.4.
