Google only lets you use app-specific passwords if you have set up two-step verification (and provided a phone number).

If you have an email client that doesn't speak OAuth and you can't/won't set up 2FA then this proxy of mine lets you use any IMAP (or POP/SMTP) client with an OAuth email provider, regardless of whether it supports OAuth 2.0 natively: https://github.com/simonrob/email-oauth2-proxy. No need for your client to know about OAuth at all.

"Just works" I run it with mbsync at the command line.

You do need a client id and some interaction with your O365 admin.

When did POP and IMAP become a “legacy protocol?” | Sep 2022
For those of us with Unix-y mail setups the move to OAuth2 can be a bit tricky, but there are now several different programs to help (spurred, I suspect in no small part, by Microsoft/Exchange's stance). The ones I know about are:

Email OAuth 2.0 Proxy <https://github.com/simonrob/email-oauth2-proxy>; mailctl <https://github.com/pdobsan/mailctl>; mutt_oauth2.py <https://gitlab.com/muttmua/mutt/-/blob/master/contrib/mutt_o...> (some suggestion that it might not always work these days?); pizauth <https://github.com/ltratt/pizauth>; oauth-helper-office-365 <https://github.com/ahrex/oauth-helper-office-365>. Disclaimer: I wrote pizauth and it's just about to move into the alpha stage.

If you don't have the time or resources to go through this process you can also use this simple proxy of mine, which intercepts the non-OAuth IMAP/SMTP commands and adds OAuth in the background: https://github.com/simonrob/email-oauth2-proxy/

If all you need is IMAP/SMTP you can use this local proxy to continue using the “less secure” app without needing app passwords: https://github.com/simonrob/email-oauth2-proxy
