Create an account and sign in

Account, company and profile: what is what

Your BuildColab account is your login: an e-mail address and a password. Creating an account does not create a company. After you sign in for the first time you either create a company or accept an invitation from one (see Create or join a company). One account can belong to several companies. Your name, photo, phone and language live on your profile (see Your profile and account security).

The sign-in and registration pages show the language last used in this browser. On a new browser they are in Bulgarian. There is no language switch on these pages; after you sign in, BuildColab switches to the language saved on your profile.

The cookie banner

On your first visit a banner appears at the bottom of every BuildColab page: "This application uses strictly necessary cookies for sign-in and security. Without them, the application cannot function." (Това приложение използва строго необходими бисквитки за вход и сигурност…). It has a Learn more (Научи повече) link to the cookie policy and one button, I accept (Приемам). There is no "decline" button because BuildColab uses only the cookies it needs to sign you in and keep you secure. Your consent is remembered in this browser, so the banner comes back in a new browser or after you clear the browser's site data.

How to create an account

Registration on the Registration (Регистрация) page has two steps. Your values are kept if you go back from step 2 to step 1.

1. Open BuildColab. If you are not signed in, the sign-in page opens. Under the form, next to "Don't have an account?" (Нямате акаунт?), click Create an account (Създаване на акаунт).
2. Step 1: fill in Name (Име), Surname (Фамилия) and email (имейл), then click Next (Напред). If you were invited to a company, use exactly the address the invitation was sent to; invitations are matched on that address.
3. Step 2: type a password (парола) and repeat it in Confirm password (Потвърдете парола). While you type, a red list under the field shows the rules your password does not meet yet; it disappears when all rules are met. Click the eye icon to show or hide what you typed.
4. Tick both required boxes: I accept the Terms and Conditions (Приемам Общите условия) and I have read the Privacy Policy (Запознат/а съм с Политиката за поверителност). Each link opens the document in a new tab.
5. Click Sign up (Регистрирай се). To correct your name or e-mail, click Back (Назад) instead.

Result: BuildColab records your acceptance of the current Terms and Privacy Policy and e-mails a confirmation link to the address you entered. The e-mail subject is "Confirm your email for BuildColab" (Потвърдете имейла си за BuildColab); it is in the language you registered in. The link is valid for 24 hours and works once. You land on the Check Your Email! (Проверете Вашия Имейл!) page.

1. The password field with the eye icon that shows or hides the password.
2. The red list of rules the password does not meet yet, for example At least 1 uppercase letter (Поне 1 главна буква).
3. The Confirm password field, which must match exactly.
4. The two required checkboxes for the Terms and Conditions and the Privacy Policy.
5. The Sign up button that creates the account; Back returns to step 1.

Password rules

The same rules apply when you register, when you set a new password after "forgot password" and when you change your password in your profile.

Cyrillic letters do not count as uppercase or lowercase letters; BuildColab counts them as special characters. So "Парола2026" fails the uppercase and lowercase rules. The leaked-password check sends only the first five characters of a scrambled (hashed) version of your password to the checking service; your password itself never leaves BuildColab.

How to confirm your e-mail address

1. Open the e-mail "Confirm your email for BuildColab" (Потвърдете имейла си за BuildColab). If it is not in your inbox, look in Spam or Promotions.
2. Click the link. The confirmation page shows "Verifying email address..." (Потвърждаване на имейл адреса...) and then "Verification successful!" (Успешно потвърждаване!).
3. Click Continue to Sign in (Продължете към Вписване) and sign in with your e-mail and password.

If the link has expired or was already used, the page shows "Verification failed" (Неуспешно потвърждаване) and a Return to Registration (Върнете се към Регистрация) button. Register again with the same e-mail address: while the address is still unconfirmed, registering again simply sends a new link instead of reporting an error.

Resending the confirmation e-mail

On the Check Your Email! page, click Resend (Изпрати отново). On success you see "Verification email was resent successfully." (Имейлът за потвърждение беше изпратен отново.). Resend only works in the same browser tab you registered in. In a new tab it answers "No active registration found to resend." (Няма активна регистрация за повторно изпращане.); in that case open the registration page and register again with the same e-mail. Back to Login (Връщане към вписване) returns to the sign-in page.

How to sign in

1. Open BuildColab. The Sign in (Вписване) page opens if you are not signed in.
2. Enter your email (имейл) and password (парола).
3. Click Sign in (Вписване).

Where you land depends on your situation:

Any sign-in error shows the message "Sign-in failed" (Неуспешно вписване). The usual causes are a wrong e-mail or password, an e-mail address that is not confirmed yet ("Email is not verified. Please check your inbox.") or a deactivated account. There is no "Remember me" option; your session stays active according to the session rules below.

1. The Create an account link that opens the registration page.
2. The email field: the address you registered with.
3. The password field with the eye icon.
4. The Forgot your password? (Забравена парола?) link that starts the password reset.
5. The Sign in button.

Session rules: why BuildColab signs you out

The BuildColab mobile app keeps its own session. Signing in on the web does not sign you out of the app. Two-factor authentication (codes from an authenticator app) is not available for BuildColab accounts; you sign in with e-mail and password only.

How to reset a forgotten password

1. On the sign-in page click Forgot your password? (Забравена парола?). The Reset Password (Възстановяване на парола) page opens.
2. Enter your e-mail address and click Send Reset Link (Изпрати линк за нулиране).
3. The page says "We have sent a password reset link. Please check your inbox." (Изпратихме линк за нулиране на паролата. Моля, проверете вашата поща.). You see this message whether or not the address has an account, so nobody can use this page to find out who is registered. If no e-mail arrives, check the address and click Resend (Изпрати отново).
4. Open the e-mail "Reset your BuildColab password" (Смяна на парола за BuildColab) and click its link. The Set a new password (Задайте нова парола) page opens.
5. Type the new password in New password (Нова парола) and again in Confirm new password (Потвърдете новата парола). The password rules above apply.
6. Click Reset password (Смени паролата). The page says "Your password has been reset." (Паролата Ви беше сменена.). Click Sign in (Вписване) and sign in with the new password.

Side effects: all your web sessions and all your mobile-app sessions end, and BuildColab e-mails a security notice "Your BuildColab password was changed" (Паролата Ви за BuildColab беше променена) with the date and time of the change. If you did not change your password, contact your administrator and reset it at once.

A reset link works once and expires. An old or used link shows "This password reset link is invalid or has expired. Please request a new one." (Този линк за смяна на парола е невалиден или изтекъл. Моля, заявете нов.) with a Send Reset Link button. The reset page opens even if someone else is signed in in the same browser, so you can reset your password from a shared computer.

How to sign out

1. Click your avatar at the far right of the top bar.
2. Click Sign out (Изход).

If the page you are on has unsaved changes, BuildColab asks before leaving. Signing out stops live updates, clears the data cached in the browser and returns you to the sign-in page. On a shared computer, always sign out when you finish.

Accepting updated Terms or Privacy Policy

When BuildColab publishes a new version of the Terms and Conditions or the Privacy Policy, every user receives an e-mail with the effective date and version of each document. The e-mail says that continuing to use BuildColab after that date counts as acceptance, and its Отвори link opens the page You need to accept the updated legal documents (Необходимо е да приемете обновените правни документи).

1. Open the link from the e-mail. If you are signed out, sign in first; you come back to the page.
2. For each document, click Preview (Преглед) to read it in a new tab, then tick its box, for example I accept the Terms and Conditions (Приемам Общите условия). Each item shows its Version (Версия).
3. Click I accept (Приемам). The button is active only when every box is ticked. You see "Thank you! Your acceptance has been saved." (Благодарим! Приемането е запазено.) and return to your projects.

If the link was sent to a different account than the one signed in, the page says "This link is for a different account" (Този линк е за друг акаунт). Click Switch account (Смени акаунт): BuildColab signs you out and brings you back to the page after you sign in with the right account.
