It's not really an option these days, most services _require_ a phone number and for some reason that is completely unknown to me, a phone number is considered as secure as a password or email address - despite sim jacking and generally losing access to your number when changing contract being very known problems.

You could use a fake phone number service, but ultimately somebody else could just use this to login to your account. You also can't guarantee you are able to use that phone number again when you need to get back in.

The only real option is to not use the service at all, which is easier said than done when your family, friends and even employers use (and require you to use) the service.
