I’ve read this nice official blogpost recently about account and key security. As it says “[T]he security measures discussed in this series are more suited to high value accounts and not frequent spending accounts because they achieve higher security, but require more effort.”
The post shows the process for operations like creating account and signing transaction on an offline machine.
The Part II. of the series confirms that single-key account creation should always be done on an offline machine, and the same is true for recovering/importing an account. My question is: how can you get to know the balance of your account, if the creation / recovering only happens offline? I thought that you have to have your account in a wallet in an online machine to sync (and show) your balance.
