I usually recommend bitwarden for strangers since I dont know how discipline they are with backups, but currently I use keepassxc on desktop and keepassdx on my android. For hardware security keys, yubikey is kinda held at the highest honor but theyre are a bit on the pricer side. Since you would need to get at least 2 (one as a backup), their more budget friend model would run you 50-60$. They also go on sale time to time but imo its worth the investment and basically a must if you use a cloud based password manager.
