I've tried using sms4sats.com several times. Never once has it worked properly without issue. I now use https://temp-number.org instead. It's a little more pricey, but works 99% of the time, so is worth it.

I bought 10 of the 1BTC coins when they were cheap, about $1 as I recall. Unfortunately I gave them all away as gifts nearly as soon as I got em. I also forgot who I gave them to, all except 1, and it's someone I never want to speak with again due to a divorce situation.

As long as your password manager isn't something that can be hacked or spied on by anyone, that should work.

I only trust open-source password managers.

https://keepassxc.org/ is my favorite.
