Managing five brands from one browser turns into a routine of signing out, signing in, and answering whatever the platform asks when it notices. The sign-in is not the cost. The cost is that every one of those switches is a fresh chance for the platform to see one machine behind several brands.
One profile per account, signed in once
Create a profile per brand account and sign in inside it once. The session stays in that profile's own browser directory, so tomorrow morning the profile opens already signed in. There is no shared cookie jar for a session to leak into.
Keep the device and the route still
A profile reports the same device identity every time it opens, because the identity is stored on the profile rather than read from your computer. Assign the proxy the account was set up on and it uses the same route as well. Both are attached to the profile, so neither is something anyone has to remember to set.
Working a brand, not a browser
- Group a brand's profiles and open the whole group at the start of the day
- Let the row tell you what is running, syncing or closed instead of hunting through windows
- Assign the scheduling and design extensions a brand needs to that brand's profiles only
- On the paid plans, Cloud Sync carries the same stored sessions to your other machine
