However, They are five important security keys in Steemit blockchain atlarge which can be used for different purpose in once steemit account and i advised it been kept safe and not to be exposed, i beter advice all steemians to better safe them offline or in your Google account manager to avoid total misplacement. Each of those keys has its vital functions and fundamental uses and hence i take my discuss on the below listed keys and its basic functionality as organized by the steemit ecosystem.

THE TYPES OF KEYS AND ITS FUNCTIONS

      POSTING KEY

posting key is a primary key,which in other words not too relevant but it shouldn't be toiled with because is it quite important basic on it functionality, as a primary key not much are required from it in terms of higher level of security,and one cant get official permission to any operations that is linked to the token in your wallet.

  OWNERS KEY 

This key serves almost as the masters and i would call it a secondary key ,but it not the masters key by any chance but can act as one in some minor cases,it is also powerful and very useful because it can be used to change any other keys on the account, including itself . You're advised to save this password offline and in any other Google account manager for safety just to avoid displacement, also external disk(memory cads) or flash drive are to be use in saving as well and we only uses it to recover a compromised account or stollen account.

This key can not be found when after you have access your wallet,nontheless but provides it been stored in a save place you cant be lose,but not a If your master password is exposed to any third party site or if someone sees it, they can steal your account and all of the finance and valuables in it. it is advice you save this password according to the saving suggestions specified for other keys and more above,if you eventually loss it you cannot recover it and thereby losing access to your steem account and wallet at large.

SUMMARY

I strongly advise you save your master password properly etc, for it is the most powerful of all password.you can only login into your account using the key with the appropriate permissions for what you are doing. If logging in with your posting key, make sure you don't overwrite it. Do not disclose your password or keys with any third party site as mentioned above and the reason for all this emphasis is for the knowledge and consciousness of holding your key safe to stick in once mind to avoid tears ,except you are sure of that site, they phishing site that has been created to steal peoples credentials are all over the net thus one need to be very careful while using your keys, so take note of this, don't fall victim. Always remember, there is no way to recover your account if you lose your master password or owner key as well. If your account is stolen you can only recover its ownership and not the funds.
In other words i for sure i have expend the essential value of all this keys and i hope i have brought to your understanding the importance of this keys.
