How can I keep my crypto wallet secure when I've lost my hardware wallet and need to access my funds on a public computer?

I totally get why you're worried about accessing your crypto funds on a public computer, especially after losing your hardware wallet. I've been in similar situations before, and it's always a bit of a panic. One thing you could try is using a browser-based wallet that doesn't require you to download any software or store any sensitive info on the public computer. Just make sure you're using a reputable wallet service and a secure connection.

Another option might be to use a mobile wallet app on your phone, if you have one set up. This way, you can access your funds without having to use the public computer at all. If you do need to use the public computer, I'd recommend using a VPN to encrypt your internet connection and protect your data from being intercepted. You should also make sure the public computer's browser and operating system are up to date, to minimize any potential security vulnerabilities.

Looking ahead, I think it's a good idea to have a backup plan in place, like a secondary wallet or a secure note with your seed phrase. This way, if you ever lose access to your primary wallet, you can still recover your funds. I've also heard of people using a "watch-only" wallet, which allows you to view your balances and transactions without being able to spend any funds - this might be a good option if you need to access your funds on a public computer in the future.

Lastly, I'd just say to be extremely cautious when using public computers for crypto transactions, and try to avoid it if possible. If you do need to use one, just make sure you're taking all the necessary precautions to protect yourself and your funds. I hope this helps, and I wish you the best of luck in getting back access to your crypto funds - I'm sure it's a huge relief when you finally do!
