Tips for using more than one SageMathCloud account

If you have more than one SageMathCloud account, sometimes you might have problems when logged into both accounts simultaneously.

The key fact is that you should not attempt to use two different sagemath.com accounts simultaneously, from the same browser. The cookies will interfere with each other. However, both Firefox and Chrome allow for two or more identities at once, where each identity has a distinct set (cookie jar?) of cookies. That approach works very well with SageMathCloud.

By the way, an easier way to say "Support for using more than one SageMathCloud account simultaneously" is "multiple identity support."

What Can go Wrong?

One phenomenon is that you might be able to access some files from one account, but not other files from that account, even from the same browser tab!

For example, you might see the error message "Opening 'filename' publically not yet supported" if you are signed into two user accounts simultaneously.

An Easy Fix when Things Get Weird:

Make sure you close all sagemath.com windows in a given browser, log out of sagemath.com entirely, and then log in again with the account that you want to use.

For Beginners, who wish to use more than one SageMathCloud account:

There are some easy ways to do this. For example, you might use one account in one browser, like FireFox, and the other account in a different browser, perhaps Google Chrome.

Or within Firefox alone, you can have one account in a normal window. Then open a "New Private Window" under the "File" menu and use the other account in that window. The browser will keep those separate.

Similarly, within Google Chrome alone, you can have one account in a normal window. Then open a "New Incognito Window" under the "File" menu and use the other account in that window. Again, the browser will keep those separate.

If you have both Firefox and Google Chrome on the same machine, you can use four accounts simultaneously this way!

For Advanced Users, who wish to use more than one SageMathCloud account:

Google Chrome refers to having multiple identities as "multiple people." Here is a link to some Google Chrome Support Pages that discuss this.

Some Firefox users manage their multiple identities via the plug-in "Multifox." Here is a link to multifox.
