AADE timologio login (e timologio eisodos), step by step

AADE login links

Check the address bar before typing credentials: the login is only at mydata.aade.gr/timologio. Detailed guides: friendly codes https://rotomal.com/en/ilektroniki-timologisi/filikoi-kodikoi/ and Subscription Key https://rotomal.com/en/ilektroniki-timologisi/subscription-key/

The two ways to log in

How to create friendly codes (φιλικοί κωδικοί) and log in

• On https://mydata.aade.gr/timologio/ click «Είσοδος με Φιλικούς Κωδικούς», then «Δημιουργία / Ανάκτηση Φιλικών Κωδικών» (create or recover friendly codes). This opens myDATAusers (https://www1.aade.gr/mydataappusers).
• Sign in with the business's TAXISnet credentials.
• Create a username and password. The username cannot be changed later; only the password can, in myDATAusers.
• Alternative path from myAADE: Εφαρμογές > Δημοφιλείς Εφαρμογές > myDATA > Φιλικοί κωδικοί και εξουσιοδοτήσεις myDATAusers (Applications > Popular applications > myDATA > friendly codes and authorisations).
• Go back to «Είσοδος με Φιλικούς Κωδικούς» and enter ΟΝΟΜΑ ΧΡΗΣΤΗ and ΚΩΔΙΚΟΣ. The same codes log you in to myDATAapp on a phone.

How to find or create your Subscription Key

• On https://mydata.aade.gr/timologio/ click «Δημιουργία / Ανάκτηση Subscription Key». The link opens AADE's myDATA platform (www1.aade.gr/saadeapps2/bookkeeper-web).
• Sign in with TAXISnet credentials and open the myDATA REST API registration form.
• If you already registered, the Subscription Key is the value in the «Κωδικός API» (API code) column of the table listing your registrations; the same row shows the «Όνομα Χρήστη» (username) that timologio asks for. That is how you find the key again if you forgot it.
• If you have no registration, click «Νέα εγγραφή» (new registration), enter a username, password and email and choose «Προσθήκη εγγραφής» (add registration). Open the confirmation link in the email you receive; AADE then issues a new Subscription Key.
• Go back to timologio and fill in ΟΝΟΜΑ ΧΡΗΣΤΗ, ΑΦΜ and Subscription Key.

What is myDATAusers?

myDATAusers (https://www1.aade.gr/mydataappusers) is the AADE application where, with TAXISnet credentials, a business creates friendly codes (username and password) for timologio and myDATAapp and manages authorisations. Password resets also happen there.

Authorised users, such as an employee or your accountant, first accept the authorisation in myDATAusers, then create their own friendly codes.

Common login problems

After your first login

• Set up the business profile, your customer list and your goods or services.
• Define document categories and invoice series.
• Issue a test invoice and check it appears in myDATA.
• Declaration: none if you issue only through timologio or myDATAapp from 2 November 2026; needed for the gradual period to 31 January 2027 (per Taxheaven, by 12 November 2026). Details are in the declaration guide.

If you want help with the login

AADE answers questions through its my1521 service (phone 1521). If you'd rather do it together on a video call in English, Τιμολόγια σε Τάξη guides you from friendly codes or the Subscription Key to your first test invoice, from €29 one-time. You type your own credentials; we never ask for or keep them.
