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.
You can log in to 10 Instagram accounts by merging them from your Facebook Business account.
@nateolsen Here I am mentioning the native app, Instagram app would allow you to manage up to 10 accounts from one mobile device. You can keep adding the accounts in the app by tapping on the + icon. There are various other ways that people can use more accounts but they all are believed to be black hat techniques.
@naomiburke Awesome thanks! I will check it out! For anyone else wanting to look into it. https://lalicat.com/
Use multiple devices: Log in to one account on one device and switch to another device to log in to the second account.
Use an Instagram management tool: There are various tools available that allow you to manage multiple Instagram accounts from one place.
Use different browsers: Log in to one account in one browser, then open an incognito or private window and log in to the second account.
Use virtual private networks (VPNs): Use a VPN service to change your device's IP address and log in to another account on the same device.
Note: Instagram limits the number of accounts you can log in to on one device, so be sure to follow their guidelines to avoid having your accounts flagged or banned.
