Never use your Master Password to login on Steemit please!
Think most are aware about some of the important security rules on this platform but just to repeat it given it happened to friend of mine that got hacked and the account was stolen. There is not much one can do apart from really being careful on some things.
- NEVER click on any link in any post, comment or wallet message before you did not investigate it is no phishing attempt Mouseover them to ensure you are aware where they link you to. If you are not sure - do NOT click.
- NEVER use your Master Password to login on Steemit - as DEFAULT use posting key! ALWAYS - only use Active Key for financial transactions - put your Master Password in a safe place (password manager, paper, engrave in a stone (but keep it somewhere no one has access!), put it in more than one safe places but make sure NOT to tell anyone where this is!
- KEEP ALL your Keys in a safe place!
- If you got hacked - use the Stolen Account Recovery tool immediately!
- Let others know your account has been hacked via the channels your connections are active so the can inform the community!
- Report scammers on https://steem.chat/channel/steemitabuse
BE CAREFUL - Do NOT DRINK OR USE DRUGS WHILE working with Keys
And put Water, Tea, Coffee and other liquids also far away from your device - it can destroy a lot. Make sure all data from your device is backed-up as well.
