You don’t need an app. Use one password. Change it every 3 months. Make it an acronym you can remember and use leetspeak. Something like:
1w4bcd144tcwst
“It was a bright cold day in April, and the clocks were striking thirteen.” ~George Orwell, 1984
But not so famous because then I could hack you. Heh.
Or use three acronyms: one for business, one for e-mail and social media, one for everything else.
Last Pass works well for me.
Probably the safest thing to do is write them down and stick the list in your desk drawer. How often do people break into your home to steal passwords?
I also have the spreadsheet itself password protected.
I have an old worn Little Oxford Dictionary on a table near my laptop and I have passwords written on some of the back pages. There is not enough info for anyone else to know what I am talking about.
I use geometric passwords. They are meaningless, but easy to type. I learned this from a teenager years ago. Example:
123edcFT
Try it on your own keyboard and you’ll see what I mean. If they made me change my password, I’d change it to:
234rfvGY
Make your password a sentence. Of course you may not get to have spaces, but it still works. Who is going to guess:
“Myfavoritewebsiteisfreerepublicdotcom” ?
or
“Ivotedforthebettercandidatein2012” ?
or
“IwasbornonOctober111955” ?
The number and type of sentences you can come up with are infinite.
I decided I would make an amusing word association with the name of the website I was creating the password for to lyric in a song, a movie or some quote. Then I created a standard convention for how I would type in this phrase. An example -
The first letter of the second word of each phrase would be capitalized.
The first letter e encountered would be replaced with a 3.
The phrase would always end with a !
Here's how I would apply this convention. Let's say the website has the word "mutual" in it....Mutual of Omaha
My password could be:
ourSacr3dhonor!
I got rather silly with my associations, and so I not only remember my passwords, they make me smile.
Good luck.
Cheers!
