Our "My Journey" study tool makes The FP a personalized lesson-tracking web app for our Members and Patrons, not just a website. Being logged into your donor account allows you to take advantage of all these study tracking tools, and many more donor benefits.
No one likes to have to login repeatedly, so our server settings actually allow you to stay logged in almost indefinitely if you follow these tips on your device:

Keep a tab open in your device’s browser
And be sure to use the "Remember me" checkbox as you login. This tab should then stay logged into The FP. When you want to use our site, go to your logged in tab instead of starting a new browser session, and use the Donor Benefits menu at the top to find what you're looking for without logging in again.
Some browser security settings on your device may still cause you to be logged out. Use tip #2 if this is happening frequently.

OR: Use an alternative browser just for The FP
Instead of your usual browser, use another browser only for feldenkraisproject.com. Put it on your device's homescreen like a dedicated app for The FP. Keep that browser's security settings wide open. (See below for why our site is not a security risk.)
Search the Apple or Google app store for other browsers such as Google Chrome, Mozilla Firefox, Opera, Brave, and DuckDuckGo.
You may need to disable private browsing features in the browser's settings, as some have it on by default.

Copy/paste links from emails
This is a big one: most folks like to listen to our lessons on their phones, and our site is optimized with this in mind.
But, on most mobile devices, clicking links in our emailed newsletters produces a new logged out browser window. For our newsletters, press and hold any link, click copy, then paste it to your logged in browser tab.
Here's how copying links appears on my phone when I long-press a link in my email app.
Or skip the newsletter links entirely: instead go to our homepage from your logged-in browser (click our logo at the top), and scroll down to What’s New.
If all else fails...

Try Nick's alternate way
You can login effortlessly as often as necessary by using password vault software. This my personal solution. Any time I encounter a password prompt on websites, the password manager on my iPhone simply scans my face and automatically logs me in.
There's native software on your phone for this (iCloud Keychain or Google Passwords), or you can use 1Password, Bitwarden, LastPass, or others. The New York Times' Wirecutter review site calls password managers essential for your security, and recommends these.
Bonus tip for free lessons:
Our free lessons can be played when you're logged out, but it's still nice to be logged in so it gets tracked in your History on My Journey. Simply click on the gray bookmark and heart icons. You'll be prompted to login, then returned back to the lesson.
With these tips you'll rarely need to log in again, literally as little as once per year, ESPECIALLY if you remember #3 above: for our newsletters, press and hold any link, click copy, then paste it to your logged in browser tab.
