How to log in multiple instagram accounts safely?

You can use some Multi Login Accounts Manager: Virtual Browser to Help you Login On Instagram In Safety.
The virtual browser is a program that allows you to mask information about your browser fingerprint and device by replacing your real digital fingerprint with the one you set up in the virtual browser.
For example, instead of being a Mozilla Firefox user with a 14" screen HP laptop, you can make yourself a digital fingerprint of an Asus laptop owner with a 15'6 screen that uses Chrome.
