The summary.
THE BROWSER SKILLS THAT SAVE MOST TIME
Finding text within a page, reopening a closed tab, and searching within one site.
Site-restricted search finds things on a website far better than most sites search themselves.
SEARCH WITH THE WORDS THE ANSWER WOULD CONTAIN
Not the words of your question. For a technical problem, search the exact error text.
BEFORE BELIEVING OR FORWARDING ANYTHING
Who published it, when, and what do they gain? A screenshot proves nothing — they are trivially fabricated.
Forwarding an untruth spreads it in your name.
THE HABIT THAT DEFEATS MOST FRAUD
Never use links in messages about accounts. Go to the site the way you normally do.
And never give a verification code to anyone, whoever they claim to be. Spelling and grammar no longer identify a fake.
USE A PASSWORD MANAGER
Unique passwords are otherwise impossible, and reuse means one breach compromises everything.
Store your recovery codes separately from the phone that generates them.
FOR EMAIL, DECIDE ONCE PER MESSAGE
Reply, file, defer or delete. File little and search for the rest.
ON CALLS, SOUND MATTERS MORE THAN PICTURE
Use a headset, and light your face from the front.
USE BROADCAST LISTS, NOT GROUPS
Groups expose your customers' numbers to each other.
