Following the news of the Yahoo hack of half a billion users (noted as the biggest data breach in history), you may be interested in some more tips regarding online security.

In their latest issue, Consumer Reports has a 10-minute digital privacy tune-up. Here are highlights and direct links for your convenience:

• Turn on automatic software updates wherever available.
• Use screen locks wherever available.
• Check where else you’ve been hacked at haveibeenpwned.com. You’ve probably been pwned. Adobe and Dropbox for me.
• Use temporary e-mail addresses. I tested their recommendation 10minutemail.com and I will definitely use it in the future for those “Give me your e-mail and get XXX” offers.
• Cover up your laptop webcam.
• Use the HTTPS Everywhere Browser Extension (available on Chrome, Firefox, Firefox for Android, and Opera). Help you use encrypted https whenever possible.
• Turn off location tracking in apps.

I would also add a reminder about free and/or cheap password managers. All of my accounts now have their own unique, complex passwords. I can’t imagine not using one anymore. I still use 1Password mostly because it was the first one I tried, but if they force me into a monthly subscription I will likely bail. I’ve heard positive things about LastPass, KeePass, Dashlane, and RoboForm.

I replaced my landline with Ooma VoIP home phone service over 6 years ago and and haven’t had a monthly bill since. This ended up being one of those deals where early adoption was rewarded. First there was no monthly fees, then it was about $1 a month, then about $3 a month. Today, buyers of the newest Ooma Telo are subject to the upfront equipment cost plus monthly taxes and fees of roughly $4.23 a month (varies by location). I’ve resisted upgrading to Telo as it would have forced me to give up my grandfathered monthly fee waiver.

If you are also a grandfathered Ooma Hub owner, you should check your e-mail for the following message titled “Important Service Update for Ooma Hub Owners”. (Thanks to the readers who asked me about this offer, as I would have probably deleted the e-mail.)

As a valued Ooma Hub owner and one of our earliest customers, we’d like to thank you for your support over the years.

As you may know, we discontinued technical enhancements and customer support for the first generation Ooma Hub product over three years ago. Recently, we made several network infrastructure upgrades for our Ooma Telo product, which unfortunately could cause Hub users to experience reduced service reliability due to the firmware limitations of the Hub.

As one of our earliest customers, we’d like to offer a special opportunity to upgrade to our latest Ooma Telo device for just $79.99 with free shipping. Plus, we’ll continue to waive the taxes and fees for the lifetime of your Telo device!1

When you upgrade to the Ooma Telo, you’ll enjoy better reliability and voice quality with PureVoice. Ooma Telo also supports HD Voice, integration with Amazon Echo, additional connectivity options like Bluetooth and Wi-Fi, and support for our whole family of accessories such as the Linx and HD2 Handset.

Okay, so $80 will get you a new Ooma Telo box and continued no monthly fees for the lifetime of the new box. Is it worth the upgrade? Some considerations…

Pros

• My Ooma Hub is now 6 years old, and the fee waiver is only for the lifetime of the device. This offer would get a a new device and thus a new “lifetime”, which ideally would extend my fee waiver.
• The Telo-exclusive features may interest you (better voice quality, Amazon Echo and Nest integration, Bluetooth and WiFi connectivity, Linx and HD2 accessories). Some folks seem to love their Amazon Echo, and using a wireless Bluetooth headset may offer valuable convenience.

Cons

• It costs 80 bucks.
• The warning of “reduced service reliability” is rather vague. I’m still satisfied with the current voice quality, although I am not a heavy user.
• Is it possible that my old Ooma unit is more reliable than the new Telo? Or am I just pushing my luck? Running for over 6.5 years x 24/7 is pretty great. I have a Macbook from 2006 that still runs fine.
• Telo Basic users have to pay extra for certain services that are included for free with Ooma Core/Hub including caller ID name (not just number) and e-mail alerts of new voicemails. It is unclear if this upgrade will cause us to lose these free features.

Bottom line. If you are a heavy Ooma user, it may be worth taking advantage of this offer to “future-proof” yourself for perhaps another 5 years or more. If like me you are a light Ooma user thanks to unlimited cellular minutes and/or robo-calling politicians, then a potential loss would not be as severe. The original Ooma Hub advertised “free monthly home phone service for life” (of the equipment), so I suppose I’ll see how long that ends up being.

Here’s an offer for 1,000 free Air Canada Aeroplan miles if you sign up for the Fairmont Hotels President’s Club loyalty program and use the enrollment code FED16 (embedded in link).

Citibank has a $400 bonus offer for new checking account customers. Here are the highlights:

• To qualify for a $400 cash bonus, open a new consumer checking account in The Citibank Account Package by 10/31/16.
• Within 30 days from the date you opened your new checking account, deposit $15,000 or more in new-to-Citibank funds into your new checking account or new or existing Citibank Savings Plus account.
• A minimum balance of $15,000 is required to be maintained in the new checking account or new or existing Citibank Savings Plus Account, for 30 consecutive calendar days following the date you made your qualifying deposit.
• The cash bonus will be credited to your new checking account within 90 calendar days from the date when you completed all offer requirements.
• To be eligible for this offer, you must not currently have a Consumer checking account with Citibank or have been a signer on or owner of a Citibank consumer checking account within the last 60 days.
• Limit of one of each offer per customer and one offer per account.

Here are details for The Citibank Account Package:

• $25 monthly service fee waived if you have $10,000 in combined average monthly balances.
• Interest rate is a tiny 0.01% APY.
• Free withdrawals from all Citibanks ATMs.
• Citibank will waive their $2.50 fee for using non-Citibank ATMs, if combined average monthly balances in eligible linked accounts are met. However, you may still be charged a fee by the ATM owner itself.
• No early account closure fee.

Let’s see… To start, you must not have had a Citibank consumer checking account within the last 60 days. Next, you’ll need to bring in $15,000 of money from a non-Citibank account, and keep it there for 30 days. You’ll need to keep $10,000 in your account to avoid the $25 monthly service fee. You’ll need to keep the account open for up to another 90 days (up to 120 days total) until the $400 bonus arrives.

It is not clear if you need to keep you account at the “Citibank Account” package level past the first 30 days. To be safe, you may want to keep it at that level ($10,000 minimum balance) until the bonus shows up. After that, you may downgrade to their Basic or Access levels with much lower minimum balance requirements, or you may choose to eventually close out the account after that if it doesn’t work for you.

Worth the effort? If you had $15,000 sitting in a 1% APY savings account, you’d earn $50 of interest over 4 months. So you could view this as $350 in extra interest over 4 months. Alternatively, if you earn $400 of interest on a $15,000 balance over 120 days (also ~4 months), that works out to roughly a 8% annualized interest rate. If you take out $5,000 after 30 days and keep $10,000 in there, your effective interest rate will be even higher, closer to 10% annualized interest rate for those 4 months. If the bonus arrives earlier, you could do better. At these assumed balance levels, you will avoid all monthly account fees. Note that the $400 will be reported on a 1099-INT form. Thus your interest is taxable as ordinary income, but any monthly fees you pay are not tax-deductible.

If you are an American Express cardholder, they have a promotion with BJ’s Wholesale Clubs that will essentially net you a free 1-year membership if you are a new BJ’s customer. The membership is discounted 50% down to $25, and then you also get a $25 gift card. Here are details taken from this PDF with promotion terms (backup copy).

Here’s how to redeem the new membership offer from BJ’s by September 30, 2016:

1. Show your American Express Card and photo identification at a BJ’s Club Member Services Desk and present this confirmation (or show the saved coupon on your phone).
2. Purchase a new 12-month BJ’s Inner Circle® or InnerCircle® Business Membership to get 50% off the regular price ($25 off the $50 membership fee, plus state and local taxes, where applicable or required by law) and receive a $25 BJ’s Gift Card.

Some customers have reported being able to use the $25 gift card itself to pay for the $25 membership, but either way it is essentially a free year membership.

Offer valid in-Club only; not valid on BJs.com. Market code AMEX25 expires 9/30/16. This offer may not be combined with other BJ’s membership offers, is not redeemable for cash and is good for new Members only. Market code AMEX25 may not be copied or transferred. Limit one offer per household. Photo identification required when applying for Membership.

The National Park Service turned 100 on August 25, 2016. From Thursday 8/25 to Sunday 8/28/16, there will be special events and free admission to all 412 national parks. Visit FindYourPark.com to find details about your nearest park.

The fee waiver includes entrance fees, commercial tour fees, and transportation entrance fees. Other fees such as reservation, camping, tours, concession and fees collected by third parties are not included unless stated otherwise.

If you can’t visit the parks in person (if even if you can), check out “The Hidden Worlds of the National Parks”. You’ll see select parks in 360-degree virtual reality thanks to a partnership between the NPS and Google. You can use Google Cardboard for the full experience, but it still very cool on a big screen with headphones. Here’s a one-minute preview video:

Finally, NASA is sharing what the US National Parks look like from the Space Station.

Finally, you may have noticed the Google Doodle of the day, which linked to a neat one-minute animated video below:

If you’re a parent of young children these days, you’re likely looking to make their screen time active and educational instead of passive. Unfortunately, free apps are often of low quality or severely restricted. Meanwhile, there are some excellent paid apps, but the cost starts adding up quickly at $2 to $10 a pop.

So it was welcome news when non-profit Khan Academy announced that they are partnering with developer Duck Duck Moose and making all of their apps completely free to download with all features. They have won 21 Parent’s Choice awards and 18 Editor’s Choice awards from Children’s Technology Review.

Here are links to all of their Android apps and all of their iPhone / iPad apps. More supposedly are in the works.

There are a lot to choose from, so here are the apps organized by awards won. Here are the Common Sense Media reviews of certain apps.

Best Buy has a sale offering 10% off prepaid phone cards. The “top-up” options include Verizon Prepaid, T-Mobile Prepaid, AT&T GoPhone, Cricket, Net 10, Virgin Mobile, Boost Mobile, TracPhone, Simple Mobile, Locus, and H20.

Cricket Wireless (uses AT&T network) offers a $40 a month plan ($35 net after $5 AutoPay credit) with unlimited talk, unlimited text, and 2.5 GB of LTE data. The data speeds are throttled to 8 Mbps for LTE and 4 Mbps for 4G HSPA+, which is still pretty fast to me but is a way that they save money. With this promo, you can buy a $40 topup card for $36, theoretically taking your net outlay down to $31 a month.

If you want to buy a lot of cards, you can stack this with the previously-available AmEx Offer for $25 off $250 at Best Buy. California residents should note that Best Buy will charge the MTS surcharge (basically sales tax) on prepaid card purchases.
