A password manager like Lastpass can help. It won't fill in passwords if you are on a fake site. The reason you see an icon next to links on Steemit is to indicate they are not on Steemit itself. Links in wallet messages should be treated with suspicion.
BTW It should be 'advice' (noun), not 'advise' (verb) in the last line.
Exactly - also use Lastpass - thanks for the hint on my shitty English :-) - correcting.
