Not an expert but assuming you entered the phrase directly into sparrow you now have a hot wallet. Which is probably less secure than a cold wallet which is a device that doesn't touch the internet directly.

Hear cold card is the best.

That way you should be able to keep your seed phrase safer.

In theory just signing and broad casting transactions shouldn't be insecure in either situation.

Its more about the risks of someone figuring out your seed phrase

I haven't done anything like that. Just talking about hypothetically about travelling with bitcoin. Not ideal to do with a hardware wallet in case it gets lost, stolen etc. But I previously reposted a good solution to the issue. Thanks for your reply. I definitely won't put my seed phrase directly into a laptop haha

If it'd the seed signer thing I've read there's some issues with using the pi platform securely compared to a dedicated device. Larger attack surface I think was the main isue.

Did you ever check out
