Are we too relaxed about giving AI agents access to our personal accounts?
More tools now ask to connect to email, calendar, cloud storage and bank-adjacent apps so an agent can act for you. Are people being too casual about handing over that access, and what is a sensible way to decide what an agent should be allowed to touch?
The worry is fair, and the reason is specific: an agent reads text from places you do not control, such as emails, web pages and shared documents. Any of that text can contain instructions, and a model with access to your inbox and drive can be talked into forwarding, deleting or sharing things. The access you grant is the access an attacker borrows.
Grant the smallest scope that does the job. Read-only where reading is enough, one folder instead of the whole drive, one calendar instead of the account. Prefer apps that let you pick scopes during sign-in, and avoid handing over a full password or a long-lived token when an OAuth connection with limited scopes exists.
Keep a person on the risky actions. Sending email, sharing files, deleting anything and paying for anything should ask for confirmation, at least until you have watched the agent behave for a while. Check the activity log now and then, and remove connections you no longer use.
Before connecting a new tool, ask three questions: who runs it, where your data goes, and how you revoke access. If you cannot answer all three, wait.
