Multilogin doesn't change browser fingerprints every minute . what they mean by that is you will have new browser fingerprints every minute for new profile created not the one you already created
also there is something you need to know about it . Multilogin Fingerprints is not Natural . many AFS actually can detect a noise has been added to this fingerprint . browserleaks easily can detect that .
having 100% Uniqueness is a bad idea by many AFS including PayPal . imagine this
PayPal have almost 1 billion Browser/Devices Fingerprint they gather from all users around the world and here you are coming to them with 100% Uniqueness device
The only Software that manage to get Natural fingerprint including smartphone profiles is Antidetect 8
Can you share a screenshot where you saw browserleaks detecting that the MultiLogin fingerpint was not natural? Were you using the free profiles or paid one?
And did you already test Antidetect 8?
There is really no BEST WAY.
Each of us might have a different approach of this.
At the end of the day, make sure you have cleans IPs and you are well organized.
