I use keepass with the app.keeweb.info frontend and a gdrive backend. keeweb.info has totp as well. Seems pretty straight forward and its free. Make the backend file accessible by link and forward a bit.ly to it and you can pull it down anywhere you have internet. Phone app works great too. Everything works offline too if gdrive isn't your thing

Every computer I normally use will have a copy of the file in the case that I can't access my gdrive (which I don't see happening really).
