No. Cited is a done-for-you service that publishes on the external channels itself, so you do not hand over the passwords to your own social, ad, or website accounts. What you provide is brand information, not account credentials.
What you actually provide
The data Cited needs is business and brand information, the materials it uses to do the work. Per the published Privacy Policy, that means your brand name, website, product details, keywords, links, logos, copy, and guidance, plus the basic account details to run your subscription.
That is information about your brand, not the keys to your accounts. There is a real difference, and it matters for security.
Why this is reassuring
Handing over logins is a common and reasonable fear. A login gives broad access to an account, which is exactly what you do not want to share widely. Because Cited publishes through its own setup rather than logging into your accounts, that risk does not arise.
So you keep control of your own accounts. You are sharing the inputs Cited needs to represent your brand, not administrative access to your systems.
Payment is handled securely too
On the billing side, payment is processed by Stripe, which handles card details directly, and Cited does not store full card numbers (Privacy Policy). So even your payment details are not sitting in Cited's own systems.
