Posting key

Posting key allows accounts to post, comment, edit, vote, share, and follow or deactivate other accounts. Most users need to log into Steemit every day by posting a key.

Active key

Active key are intended for more sensitive tasks such as transferring funds, increasing / decreasing, converting Steem Dollars, giving votes to watch, updating detailed profiles and pictures, and placing market orders.

Owner key

Owner key is only intended to be used when needed. This is the strongest password because it can change any password, including the owner key. We recommend that you store this password offline, and only use it to recover compromised accounts.

Memo key

This password is used to encrypt and decrypt memos when transferring funds. To encrypt a memo, use the previous / # sign.
