First, the password was set to “abcd” with trytond-admin. Then the database query of the table res_user for “admin” returned the password_hash “$argon2id$v=19$m=65536,t=3,p=4$LGWMkRJijHEO4XzvnXMuJQ$KgH7IRbztZwfrsyvI/W2/mzNUpCpWlQ/laCU1KbuW8g”. Further the password “abcd” was encrypted with “PasswordHasher” and both hashes were identical. Now the login was attempted with the user “admin” and the password “abcd”, but every time “OK” was pressed, the prompt “Password for admin” appeared again and again in an endless loop. To avoid any queries: every care was taken to ensure that the password “abcd” was entered correctly and the Caps Lock button was not activated.
