You can go into your account and under two-step, generate a one-time code. Store that code somewhere secure, like a note in your password manager if you trust it with both steps, and you can do it.
Pretty sure Google authenticator will have something equivalent but likely more secure, but haven’t used it.
I have never heard of anything secure doing that. Assuming they have taken security steps, it would mean they recorded those characters in plaintext when you set your password, but that means that at least those characters aren’t secure, and a breach means some hacker has a great hint.
When the hashing occurs, it happens using the code you downloaded when you visit the site, so it’s your computer that does the hash, and then just the hash is sent onwards, so they can’t just pull the letters out of a properly secure password.
A secure company would use two-factor authentication to verify you above and beyond your password, anyway, since a compromised password somewhere else automatically compromises questions about your password.
