My mum's phone was stolen last week, got her a new phone two days later but couldn't login to her gmail account while setting up the new phone. I created the email myself, so I retrieved her password from bitwarden but couldn't login. Confused, I tried the same password multiple times, then tried the 'forgot password' feature, entered her phone number and got another shock when google asked me to get a code from my samsung galaxy S20 app - I don't use galaxy. Google refused to send a reset code to her phone number even when I provided the original password. Turns out she needed some contacts the previous day and asked my siblings for help. They used the forgot password feature, got a code through the retrieved SIM card, changed the password and logged in through an app on a samsung galaxy phone. It's crazy, someone who didn't know the password could change it. But I who had both the original password and the SIM card but couldn't. We'd have lost her contacts if it was thief who changed her password before we retrieved her SIM card.
