Hello there @fernandoylet five questions were asked but it seems you only answered three of them, here's a list of the questions, please edit your post and answer all of them.
How much do you know about the security keys of Hive?
Do you have enough idea about the importance of these keys?
Do you know how to locate security keys of Hive?
What are the functions/permissions of each keys and explain them?
What measures have you taken to keep your keys safe?
Hi @prayzz, I have embedded my answers in the following way...
The whole post shows how much I know about the security keys of Hive. Like how easy is to find them and what each key is for.
"Hive interfaces may ask for permission to use one or more of your keys as needed"
"Hive have all passwords or keys available inside the wallet"
"There is a memo key to encrypt and decrypt memos; a posting key to post, comment, vote or follow other users; an active key to transfer funds; and a master key with all the functions"
"As a casual user, I keep copies of my keys in a couple of separate files. Those copies are usefull when loging from other devices. Anyhow, a few months from now those copies could be lost or forgotten. Therefore, it makes more sense to invest our time in a system where we know where to find the keys without delay"
Since my intention is to answer the questions while maintaining the interest and attention of my readers, I added at the end a link pointing to your tutorial.
