[gears-users] Gear database access and security

[fvisticot]

I have read some post related to the security pb linked to the gear
database.
I have created an application who store customer infos in the gear db.
What is the solution to protect the access of this db only for this
customer ?
Is it possible to access this db with login / pwd ?
Is there other solution to restrict the db access ?
Is something planed in next releases ?
